Abstract
Embodiments include a DRAM cache structure, associated circuits and method of operations suitable for use with high-speed caches. The DRAM caches do not require regular refresh of its data and hence the refresh blank-out period and refresh power are eliminated, thus improving cache availability and reducing power compared to conventional DRAM caches. Compared to existing SRAM caches, the new cache structures can potentially achieve the same (or better) speed, lower power and better tolerance to chip process variations in future process technologies.
