Abstract
Embodiment herein describe read and write assists for SRAM cells. When performing a write operation, a write assist technique can be performed on the SRAM macro where a word line (WL) for the selected row is boosted to a voltage above the voltage supply. In addition, cell supply voltages for unselected columns are boosted to prevent the boosted WL from flipping bit values in unselected cells. When performing a read operation, a read assist technique can be performed on the SRAM macro, where the Vcell for the selected column is boosted to a voltage above the voltage supply. In another embodiment, the WL for the selected row of the read operation can also be boosted for enhancing the read performance.
