The design is for a BTI-Aware SRAM. A write wordline (WWL) voltage level control scheme is design to lower the WWL voltage before the half-selected cell stability fail due to BTI degradation. The beneficial of the scheme is it recovers the degraded cell stability without changing any SRAM's initial operating parameters.
