Abstract :
The predominant concern for SRAM cell designers is stability for nano-scaled technology due to the reduction in power supply voltages. We propose two novel SRAM cells, based on the Schmitt Trigger at 65 nm feature size in CMOS. This achieves 4–5.35 times higher read static noise margin (VDD = 350 mV) compared to the conventional 6T cell design. It also provides the much desired greater enhancement in stability compared with three other reported SRAM cell designs.
