This paper describes a high-performance low V(MIN) SRAM with a disturb-free 8T cell. The SRAM utilizes single-ended buffer Read, and cross-point data-aware Write Word-Line structure with adaptive VVSS control to eliminate Read disturb and Half-Select disturb, thus facilitating bit-interleaving architecture and achieving low V(MIN). A 512Kb test chip is implemented in UMC 55nm Standard Performance (SP) CMOS technology. The measurement results demonstrate operating frequency of 943MHz at 1.2V VDD and 209MHz at 0.6V VDD.
