A Reliable Low Standby Power 10T SRAM Cell with Expanded Static Noise Margins

This paper explores a low standby power 10T (LP10T) SRAM cell with high read stability and write-ability (RSNM/WSNM/WM). The proposed LP10T SRAM cell uses a strong cross-coupled structure consisting standard inverter with a stacked transistor and Schmitt-trigger inverter with a double-length pull-up transistor. This along with the read path separated from true internal storage nodes eliminates the read-disturbance. Furthermore, it performs its write operation in pseudo differential form through write bit line and control signal with a write-assist technique. This entire design was simulated using H-Spice/tanner 16nm CMOS Technology.
