Abstract
A memory includes an array of active memory cells arranged in rows and columns, and at least one dummy memory cell column adjacent the array of active memory cells. A sensing circuit is coupled to the at least one dummy memory cell column to sense at least one variation associated with the at least one dummy memory cell column. An assist circuit is coupled to the array of active memory cells. An assist determination controller is coupled to the sensing circuit to store a look-up table of output assist values corresponding to different variations associated with the at least one dummy memory cell column, to determine an output assist value from the look-up table based upon the at least sensed variation, and to operate the assist circuit based upon the determined output assist value.
