Abstract
A dual word-line level shifter circuit and associated SRAM. A circuit is disclosed that includes a first transistor gated by a data input at the lower voltage, and a second transistor gated by a restore input at the higher voltage, wherein the first and second transistors are coupled along a series path to a source at the higher voltage; a control node along the series path; an output node coupled to the control node via a first pair of parallel transistors; and a feedback circuit having a second pair of parallel transistors and a feedback transistor, wherein the feedback transistor couples the second pair of parallel transistors to the control node and is gated by the output node.
