SRAM (Static RAM)
Faster, more expensive memory than DRAM that needs no refresh; used for on-chip caches close to the processor.
SRAM (Static RAM) is a memory type that is faster and more expensive than DRAM and does not require constant refreshing. It is used for on-chip caches that sit closest to the processor cores, where speed matters more than density. SRAM scaling has slowed at advanced nodes, making on-chip cache an increasingly precious and cost-driving resource in modern accelerators. See Memory Wall 101.
