Abstract
A memory circuit includes an array including a plurality of memory cells arranged across a plurality of columns and a plurality of voltage control circuits, each of the plurality of voltage control circuits operatively coupled to the memory cells of a corresponding one of the plurality of columns. Each of the plurality of voltage control circuits includes a first portion configured to provide a first voltage drop in coupling a supply voltage to the memory cells of the corresponding column and a second portion configured to provide a second voltage drop in coupling the supply voltage to the memory cells of the corresponding column. The first voltage drop is substantially smaller than the second voltage drop.
