  • We propose a novel Schmitt trigger (ST) based differential 10-transistor SRAM (static random access memory) bitcell suitable for subthreshold operation. The proposed Schmitt trigger based bitcell achieves 1.56 x higher read static noise margin (SNM) ( Vdd = 400 mV) compared to the conventional 6T cell. The robust Schmitt trigger based memory cell exhibits built-in process variation tolerance that gives tight SNM distribution across the process corners. It utilizes differential operation and… CONTINUE READING
