A 256kb 6T Self-Tuning SRAM with Extended 0.38V-1.2V Operating Range using Multiple Read/Write Assists and VMIN Tracking Canary Sensors

This work shows a closed loop self-tuning 256kb 6T SRAM with super-threshold to sub-threshold 0.38V-1.2V extended operating range using combined read and write assists and in-situ dynamic VMIN tracking canary sensors. A 337X power reduction is achieved using multiple combined peripheral assists and an additional and 4.3X power reduction is achieved using VMIN tracking canary sensors, respectively. Combining both methods saves 1444X in active power and 12.4X in leakage at the 0.38V.
