Abstract
Various SRAM non-clamping write driver with write-assist are disclosed, including a write driver circuitry that does not clamp the Bitlines (BLs) during the write operations, and a negative BL Write-Assist (WA) circuit that provides a negative BL boost desirable for use with high-density bit cells. When used with memories other than those having high-density bit cells, the negative BL WA improves the minimum voltage (Vmin) and frequency of operation.
