Abstract :
In this paper, we propose a pulse-controlled dynamic voltage scaling (PC-DVS) scheme in an SRAM macro to suppress leakage power consumption to reduce total power. The proposed SRAM macro is capable of operating in low-voltage regime with high variation immunity. The proposed PC-DVS scheme reduces the array power up to 62% at 500 kHz while the selected sub-bank operating at 0.5 V and the unselected sub-banks Hold data at 0.35 V.
