Abstract
In a first aspect, a level shifter circuit for use in a memory array is provided that includes (1) a first voltage domain powered by a first voltage; (2) a second voltage domain powered by a second voltage; (3) level shifter circuitry that converts an input signal from the first voltage domain to the second voltage domain; and (4) isolation circuitry that selectively isolates the first voltage domain from the second voltage domain so as to selectively prevent current flow between the first voltage domain and the second voltage domain. Numerous other aspects are provided.
