Low Voltage Low Power SRAM Design Based on Schmitt Trigger Technique

Now-a-days, electronic devices are portable which requires low power/low voltage requirement to maximize the battery lifetime. The authors propose Schmitt Trigger based SRAM bitcell that can operate on low supply voltages. The proposed Schmitt trigger SRAM bitcell resolves the fundamental conflicting design requirement of read versus write operation of conventional 6T bitcell and it gives better read-stability as well as better write ability compared to the other bitcell. This paper is executed under the Mentor Graphics EDA tools in 350nm, 250nm CMOS technology. ST-2 cell consumes less power than ST-1 cell.
