An apparatus and method are provided for implementing write assist with boost attenuation for static random access memory (SRAM) arrays. The apparatus includes a memory array comprising a plurality of SRAM cells. The apparatus further includes a write driver connected to each of a differential pair of bit lines in each of the plurality of SRAM cells of the memory array. The apparatus further includes a write assist attenuation circuit connected to the write driver, the write assist attenuation circuit comprising a clamping device configured to modify a control signal as a function of supply voltage and process to attenuate an amount of boost applied to pull one of the bit lines below ground in an active phase of a write cycle.
