Tachyum^® today announced that it has successfully enabled DRAM Failover correct system on its Prodigy Universal Processor, demonstrating enhanced reliability for even larger-scale AI and HPC applications even in the case of DRAM chip failures.

Tachyum’s DRAM Failover is an advanced memory error correction technology that improves the reliability of DRAM and provides a higher level of protection than traditional Error Correction Code (ECC). DRAM Failover can correct multi-bit errors within a single memory chip or across multiple memory chips, allowing continued memory operation in the event of device-level faults in memory. With DRAM Failover, even a whole DRAM chip failure can be tolerated without affecting the system and applications.

Because they help preserve customer data and maintain system availability, correct systems like DRAM Failover have become popular among HPC systems and high-end servers with large memory capacities. In the case of AI clusters reaching 100,000 accelerators, the time between failures is hours—scaling to even larger AI clusters presents a major reliability challenge.

A single Prodigy processor with 640 or 1280 DRAM chips attached would mean 64,000,000 DRAM chips, a significant scale. With DRAM Failover correct, a failing DRAM die per DIMM would not affect the operation of the system and will not cause failure with Prodigy, unlike GPU accelerators.

Tachyum’s DRAM Failover validation responds to the market’s interest in large-scale AI, including Cognitive AI and Artificial General Intelligence (AGI), and signals the company’s dedication to robust Reliability, Accessibility and Serviceability (RAS) features.

“This capability is essential to increase the scale of AI training as it moves from Large Language Models and Generative AI to much bigger systems needed for Cognitive AI and AGI,” said Dr. Radoslav Danilak, founder and CEO of Tachyum. “The importance of using DRAM Failover on Tachyum’s platform will be even more evident as we increase memory capacity per Prodigy processor with every generation.”

For example, AI innovator DeepSeek is enabling open-source LLMs to scale with DRAM capacity rather than bandwidth, making DeepSeek a compelling use case for Prodigy. DeepSeek’s efficiency makes its technology more akin to how a human brain works: only a fraction of neurons fire in response to stimuli. As this paradigm is increasingly adopted by the industry, and improves over time, the benefits of ever-bigger DRAM capacity—without the reliability challenges—will further establish the advantages of Prodigy.

As a Universal Processor offering industry-leading performance for all workloads, Prodigy-powered data center servers can seamlessly and dynamically switch between computational domains (such as AI/ML, HPC, and cloud) with a single homogeneous architecture. By eliminating the need for expensive dedicated AI hardware and dramatically increasing server utilization, Prodigy reduces CAPEX and OPEX significantly while delivering unprecedented data center performance, power, and economics. Prodigy integrates 256 high-performance custom-designed 64-bit compute cores to deliver up to 18x the highest performing GPU for AI applications, 3x the performance of the highest-performing x86 processors for cloud workloads, and up to 8x that of the highest performing GPU for HPC.

About Tachyum

Tachyum is transforming the economics of AI, HPC, public and private cloud workloads with Prodigy, the world’s first Universal Processor. Prodigy unifies the functionality of a CPU, a GPU, and a TPU in a single processor to deliver industry-leading performance, cost and power efficiency for both specialty and general-purpose computing. As global data center emissions continue to contribute to a changing climate, with projections of their consuming 10 percent of the world’s electricity by 2030, the ultra-low power Prodigy is positioned to help balance the world’s appetite for computing at a lower environmental cost. Tachyum received a major purchase order from a US company to build a large-scale system that can deliver more than 50 exaflops performance, which will exponentially exceed the computational capabilities of the fastest inference or generative AI supercomputers available anywhere in the world today. Tachyum has offices in the United States, Slovakia and the Czech Republic. For more information, visit https://www.tachyum.com/.
