Memory modules with ultra-high reliability for demanding compute applications

SMART Modular Technologies, Inc. has introduced its ultra-high reliability memory solution, Zefr ZDIMM memory modules. ZDIMM modules are ideal for data centres, hyperscalers, HPC platforms, and other environments that run large memory applications that demand maximum availability for the compute platform. Memory reliability is a critical factor in data centres due to the high costs associated with downtime. These modules are offered in DDR4-3200 and DDR5-5600 form factors and are obtainable in mainstream densities.

ZDIMM modules employ the company's proprietary Zefr screening process that supplies the highest levels of uptime and reliability, typically performing 90% better than industry standard memory modules. They undergo a screening process that reproduces real-world conditions, which ensures the robustness and resilience of the modules in the most demanding computing scenarios.

"The industry standard for defective parts per million, or DPPM, for DRAM modules, is in the 3,000 to 5,000 range," explains Tom Quinn, SMART's senior vice president of business development. "Typical Zefr ZDIMM module DPPM ranges from 200 to 300. This ultra-high reliability is valuable in critical data processing environments where uptime is paramount, and downtime costs can quickly escalate."
