This paper deals with the design opportunities of Static Random Access Memory (SRAM) for lower power consumption and propagation delay. Initially, the existing SRAM architectures are investigated, and thereafter a suitable basic 6T SRAM structure is chosen. The key to low power dissipation in the SRAM data path is to reduce the signal swings on the highly capacitive nodes like the bit and data lines. While designing the SRAM, techniques such as circuit partitioning, divide word line and low power layout methodologies are reviewed to minimize the power dissipation.
