Application-specific SRAM Using Output Prediction And Statistically-Gated Sense Amplifier

This work proposes an application-specific SRAM design targeted towards video and imaging applications where data stored in the memories is highly correlated. The design utilizes this correlation to reduce bit-line switching activity and uses signal statistics to implement a statistically-gated sense-amplifier approach to achieve up to 1.9× lower energy/access when compared to a standard 8T bit-cell based design. Test chip features 32Kb of the proposed design along with 32Kb of the standard 8T design to provide on-fly comparisons of energy/access between the two implementations.
