Variation Tolerant Differential 8T SRAM Cell for Ultralow Power Applications.

Low power and noise tolerant static random access memory (SRAM) cells are in high demand today. This paper presents a stable differential SRAM cell that consumes low power. The proposed cell has similar structure to conventional 6T SRAM cell with the addition of two buffer transistors, one tail transistor and one complementary word line. Due to stacking effect, the proposed cell achieves lower pow...
