Abstract

Approaches for providing write-assist boost for a Static Random Access Memory (SRAM) array are provided. A circuit includes a write driver of a Static Random Access Memory (SRAM) array. The circuit also includes a boost circuit that dynamically varies a write-assist boost voltage based on a stability assist setting applied to a wordline of the array.
