Addressing Read-Disturbance Issue In STT-RAM By Data Compression And Selective Duplication


In deep sub-micron region, STT-RAM (spin transfer torque RAM) shows read-disturbance error (RDE) which presents acrucial reliability challenge. We present SHIELD, a technique to mitigate RDE in STT-RAM LLCs (last level caches). SHIELD uses datacompression to reduce cache-write traffic and restore requirement. Also, SHIELD keeps two copies of data blocks compressed to lessthan half the block si... » read more

Sorting Out Next-Gen Memory


In the data center and related environments, high-end systems are struggling to keep pace with the growing demands in data processing. There are several bottlenecks in these systems, but one segment that continues to receive an inordinate amount of attention, if not part of the blame, is the memory and storage hierarchy. [getkc id="92" kc_name="SRAM"], the first tier of this hierarchy, is... » read more

Universal Memories Fall Back To Earth


By Mark LaPedus Ten years ago, Intel Corp. declared that flash memory would stop scaling at 65nm, prompting the need for a new replacement technology. Thinking the end was near for flash, a number of companies began to develop various next-generation memory types, such as 3D chips, FeRAM, MRAM, phase-change memory (PCM), and ReRAM. Many of these technologies were originally billed as “uni... » read more
