ScaleFlux’s Cutting-Edge ECC Technology Set to Revolutionize DRAM Reliability

Published

on

ScaleFlux is set to transform AI and data center RAS (reliability, availability, and serviceability) with its groundbreaking ECC (Error Correction Coding) technology. As conventional ECC methods buckle under the pressure of climbing memory error rates, undermining system reliability, ScaleFlux’s innovative approach using list decoding shatters the limitations, offering rapid and efficient correction of complex errors. This disruptive technology not only boosts DRAM reliability and security but also slashes costs by making use of lower-cost DRAM chips viable, paving the way for a more resilient and cost-effective computing infrastructure. ScaleFlux is not just meeting the demands of the future—it’s redefining them.

MILPITAS, Calif., June 12, 2024 /PRNewswire-PRWeb/ — The fact that the global AI market is set to add $15.7 trillion to the world economy by 2030 (1) means that the rapidly evolving landscape of data centers and artificial intelligence (AI) technology makes the need for reliable, high-performance memory solutions more critical than ever to avoid the increasing costs of downtime from component and system failures. “Under the combination of growing DRAM densities and increasing challenges with DRAM error rates, we saw the need for a new style of error correction coding,” said Tong Zhang, Chief Scientist of ScaleFlux. He continued, “the hyperbolic growth of AI infrastructure and the emergence of memory expansion with Compute Express Link (CXL) has the cascading effect of driving up DRAM capacities and traffic, exacerbating the need for innovation in ECC.”

“ScaleFlux’s groundbreaking ECC technology is set to transform AI and data center reliability. Using innovative list decoding, it overcomes the limitations of conventional ECC methods under rising memory error rates, enhancing DRAM reliability and cutting costs.”

As DRAM technology advances towards 10nm and beyond and the error rates in the media grow, the need for DRAM fault tolerance becomes increasingly paramount. This is where error correction coding (ECC) steps in, playing a vital role in ensuring the reliability of the data and, subsequently, the data centers. Without this crucial error correction, data can readily become corrupted, resulting in “garbage in, garbage out” calculations and even costly system crashes. Traditional ECC methods face challenges in handling these increased error rates while meeting the stringent latency constraints. A new solution is needed.

Error Rates on the Rise
Four key trends are multiplying the frequency of memory errors:

1. Increasing memory capacity density: Current server and GPU systems can support a terabyte (1TB) or more of DRAM! This capacity expands even further with Compute Express Link (CXL) memory modules.
2. Increasing fault-caused blast radius: As Cloud computing infrastructure continues to scale out, the crash of one server caused by memory errors will potentially compromise more and more connected servers. This will many-fold amplify the fatal impact of memory bit errors.
3. Increasing memory access speeds: As the industry has progressed from DDR3 through DDR4 to DDR5, transfer rates have quadrupled from 1600Mb/s to 6400Mb/s with further accelerations on the way.
4. Increasing vulnerability to soft errors and defects in the memory media: As memory manufacturers move to newer manufacturing lithography, the memory bit cells shrink, introducing more susceptibility (2) to soft errors and defects.

Considering that errors per second are a function of the memory capacity, the blast radius, the rate of access to the memory, and the inherent rate of errors in the memory media the increases in all these factors clearly makes for a significant challenge to reliability.

Throw on top of that the combination of increasing complexity of error detection with the system-level performance hits from uncorrectable errors and it’s a real nightmare situation for maintaining system reliability and avoiding costly downtime.

Conventional ECC can no longer cut it
The conventional ECC methods typically follow minimum distance bounded decoding, capable of correcting up to ‘t’ symbol errors using ECC with a minimum distance of ‘2t+1’. To meet stringent latency constraints, many DRAM ECC design solutions protect each data access unit (e.g., 64-byte cache line) by interleaving multiple short-length ECC codewords that each correct only 1 or few symbols at very low latency (1~3 clock cycles).

However, when it comes to tolerating more errors from DRAM devices, conventional methods will become largely inadequate, leading to uncorrectable errors and hence catastrophic failures in data centers.

In layman’s terms, think of computer’s memory like a document. ECC functions as a spell checker, detecting and correcting errors like typos that may occur when saving or retrieving data. However, conventional ECC, like a basic spell checker, has its limitations. It can only catch and fix certain types of errors, like single-letter mistakes. If multiple errors occur or the errors are too complex, conventional ECC may struggle to correct them effectively, leaving your data vulnerable to inaccuracies.

Enter an innovative ECC methodology
ScaleFlux, a fabless semiconductor company innovating in the field of data center storage and memory technology, has developed a groundbreaking ECC solution that will revolutionize DRAM fault tolerance. ScaleFlux presented this solution at the IEEE RAS in Data Centers Summit on June 12, 2024. Unlike conventional ECC approaches, ScaleFlux’s solution leverages list decoding, a branch of coding theory with origins dating back to the 1950s but largely forgotten in modern applications due to its computational complexity.

Central to ScaleFlux’s innovation is the application of list decoding, which aims at correcting more-than-‘t’ errors. ScaleFlux’s solution departs from the conventional ECC paradigm by protecting each 64-byte cache line with a single codeword while ensuring decoding latency as low as 1~3 clock cycles. This approach enables the correction of more-than-‘t’ errors from any combination of two DRAM devices at very high speed and with low computational complexity. Moreover, list decoding offers the added benefit of avoiding mis-correction by detecting decoding errors when the list contains two codewords of similar likelihood.

To realize this innovative ECC technology, ScaleFlux developed a robust mathematical framework to analyze correction, detection, and mis-correction probabilities. They also engineered a highly parallel VLSI-friendly architecture for ultra-low-latency decoding. Successful demonstrations on FPGA platforms verified more-than-‘t’ error correction with extremely low mis-correction probability. As a part of the development effort, ScaleFlux collaborated with key ecosystem partners including memory suppliers, CPU vendors, and hyperscalers.

“Innovations like ScaleFlux’s decoding ECC methodology may be capable of enabling high-reliability CXL solutions,” said Jim Pappas, CXL Consortium Chairperson. “CXL technology-based advancements ultimately enable the industry to meet the demands of expanding memory capacity and bandwidth.”

Remember, it’s not just about memory
The impact of ScaleFlux’s ECC technology extends beyond improving DRAM reliability. By accommodating less reliable, lower-cost DRAM chips, it can reduce the total cost of ownership (TCO) for data center operators. Furthermore, it enhances immunity to security risks associated with malicious DRAM RowHammer attacks, bolstering data center security.

ScaleFlux’s innovative ECC design solution is set to revolutionize DRAM fault tolerance, offering new levels of reliability and performance benefits for computing infrastructure. With its potential to lower costs, enhance security, and push the boundaries of RAS (Reliability, Availability, and Serviceability), this technology is poised to shape the future of data center and AI computing infrastructure.

Summing it up
ScaleFlux’s ECC technology represents a significant advancement in DRAM fault tolerance, addressing the challenges faced by data centers while unlocking new possibilities for innovation at the system level. “As we embark on this journey towards more resilient and efficient computing infrastructure, ScaleFlux’s innovations are blazing the trail for progress in the ever-evolving landscape of AI and data center technology,” says JB Baker VP of Products at ScaleFlux.

NASA Awards $1.5 Million at Watts on the Moon Challenge Finale

Published

on

By

WASHINGTON, Sept. 20, 2024 /PRNewswire/ — NASA has awarded a total of $1.5 million to two U.S. teams for their novel technology solutions addressing energy distribution, management, and storage as part of the agency’s Watts on the Moon Challenge. The innovations from this challenge aim to support NASA’s Artemis missions, which will establish long-term human presence on the Moon.

This two-phase competition has challenged U.S. innovators to develop breakthrough power transmission and energy storage technologies that could enable long-duration Moon missions to advance the nation’s lunar exploration goals. The final phase of the challenge concluded with a technology showcase and winners’ announcement ceremony Friday at Great Lakes Science Center, home of the visitor center for NASA’s Glenn Research Center in Cleveland.

“Congratulations to the finalist teams for developing impactful power solutions in support of NASA’s goal to sustain human presence on the Moon,” said Kim Krome-Sieja, acting program manager for NASA Centennial Challenges at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “These technologies seek to improve our ability to explore and make discoveries in space and could have implications for improving power systems on Earth.”

The winning teams are:

First prize ($1 million): High Efficiency Long-Range Power Solution of Santa Barbara, CaliforniaSecond prize ($500,000): Orbital Mining Corporation of Golden, Colorado

Four teams were invited to refine their hardware and deliver full system prototypes in the final stage of the competition, and three finalist teams completed their technology solutions for demonstration and assessment at NASA Glenn. The technologies were the first power transmission and energy storage prototypes to be tested by NASA in a vacuum chamber mimicking the freezing temperature and absence of pressure found at the permanently shadowed regions of the Lunar South Pole. The simulation required the teams’ power systems to demonstrate operability over six hours of solar daylight and 18 hours of darkness with the user three kilometers (nearly two miles) away from the power source.

During this competition stage, judges scored the finalists’ solutions based on a Total Effective System Mass (TESM) calculation, which measures the effectiveness of the system relative to its size and weight – or mass – and the total energy provided by the power source. The highest-performing solution was identified based on having the lowest TESM value – imitating the challenges that space missions face when attempting to reduce mass while meeting the mission’s electrical power needs.

Team H.E.L.P.S. (High Efficiency Long-Range Power Solution) from University of California, Santa Barbara, won the grand prize for their hardware solution, which had the lowest mass and highest efficiency of all competitors. The technology also featured a special cable operating at 800 volts and an innovative use of energy storage batteries on both ends of the transmission system. They also employed a variable radiation shield to switch between conserving heat during cold periods and disposing of excess heat during high power modes. The final 48-hour test proved their system design effectively met the power transmission, energy storage, and thermal challenges in the final phase of competition.

Orbital Mining Corporation, a space technology startup, received the second prize for its hardware solution that also successfully completed the 48-hour test with high performance. They employed a high-voltage converter system coupled with a low-mass cable and a lithium-ion battery.

“The energy solutions developed by the challenge teams are poised to address NASA’s space technology priorities,” said Amy Kaminski, program executive for Prizes, Challenges, and Crowdsourcing in NASA’s Space Technology Mission Directorate at NASA Headquarters in Washington. “These solutions support NASA’s recently ranked civil space shortfalls, including in the top category of surviving and operating through the lunar night.”

During the technology showcase and winners’ announcement ceremony, NASA experts, media, and members of the public gathered to see the finalist teams’ technologies and hear perspectives from the teams’ participation in the challenge. After the winners were announced, event attendees were also welcome to meet NASA astronaut Stephen Bowen.

The Watts on the Moon Challenge is a NASA Centennial Challenge led by NASA Glenn. NASA Marshall Space Flight Center manages Centennial Challenges, which are part of the agency’s Prizes, Challenges, and Crowdsourcing program in the Space Technology Mission Directorate. NASA contracted HeroX to support the administration of this challenge.

Disparities Narrowing Among Patients Undergoing Blood Stem Cell Transplant, Roswell Park Study Reveals

Published

By

Historically, some patients with blood cancers have been less likely than others to receive stem cell transplant, also known as bone marrow transplant. Theresa Hahn, PhD, of Roswell Park is lead author of a new study showing that older adults and Black patients are much less likely than people from other groups to receive a blood stem cell transplant.

BUFFALO, N.Y., Sept. 20, 2024 /PRNewswire-PRWeb/ —

Study led by Dr. Theresa Hahn published in JAMA Network OpenNumber of transplants for blood cancers rose from 2009 to 2018Research team analyzed trends in transplant utilization for that period

Every year, more than 22,000 patients in the U.S. undergo a potentially lifesaving blood stem cell transplant — often called a “bone marrow transplant” — for the treatment of hematologic diseases. But historically, some patients with blood cancers have been less likely than others to receive the treatment. Theresa Hahn, PhD, of Roswell Park Comprehensive Cancer Center is lead author of a new study in the journal JAMA Network Open showing that while progress has been made in reducing those disparities, older adults and Black patients are much less likely than people from other groups to receive a blood stem cell transplant.

“This study shows that while progress has been made to reduce disparities among racial and ethnic groups, there’s a need to improve hematopoietic cell transplant utilization rates in older adults and in Black patients of all ages.” — Theresa Hahn, PhD, Roswell Park Comprehensive Cancer Center

The research team analyzed data provided by the Center for International Blood and Marrow Transplant Research (CIBMTR) for 136,280 patients who underwent hematopoietic cell transplant (HCT) in the U.S. between 2009 and 1018, comparing those numbers with the incidence of six blood cancers (acute myeloid and lymphoblastic leukemia, multiple myeloma, Hodgkin and non-Hodgkin lymphoma and myelodysplastic syndrome) in various age, race and ethnic groups the U.S. as reported by the National Cancer Institute’s Surveillance Epidemiology and End Results (SEER) Program.

The team found that during that period, the use of HCT increased for the treatment of most blood cancers — and rose among all age, race and ethnic groups.

The researchers also discovered that in the most recent years analyzed, from 2017-2018:

The rate of HCT utilization for blood cancers rose among Hispanic and younger patients to equal the rate of non-Hispanic white patients.Non-Hispanic Black patients had a lower rate of HCT for all six diseases studied.Pediatric, adolescent and young adult patients had a higher rate than adult patients of allogeneic HCT, which involves receiving cells from a healthy donor.

“This study shows that while progress has been made to reduce disparities among racial and ethnic groups, there’s a need to improve hematopoietic cell transplant utilization rates in older adults and in Black patients of all ages,” says Dr. Hahn, Professor of Oncology in the Department of Cancer Prevention and Control at Roswell Park and the study’s first author.

The research team also include Dr. Hahn’s Roswell Park colleague Megan Herr, PhD, and collaborators from the Medical College of Wisconsin, Milwaukee; the CIBMTR; and the Mayo Clinic.

From the world’s first chemotherapy research to the PSA prostate cancer biomarker, Roswell Park Comprehensive Cancer Center generates innovations that shape how cancer is detected, treated and prevented worldwide. Driven to eliminate cancer’s grip on humanity, the Roswell Park team of 4,000 makes compassionate, patient-centered cancer care and services accessible across New York State and beyond. Founded in 1898, Roswell Park was among the first three cancer centers nationwide to become a National Cancer Institute-designated comprehensive cancer center and is the only one to hold this designation in Upstate New York.
