Abstract
Described is an apparatus and system for improving write margin in memory cells. In one embodiment, the apparatus comprises: a first circuit to provide a pulse signal with a width; and a second circuit to receive the pulse signal and to generate a power supply for the memory cell, wherein the second circuit to reduce a level of the power supply below a data retention voltage level of the memory cell for a time period corresponding to the width of the pulse signal. In one embodiment, the apparatus comprises a column of memory cells having a high supply node and a low supply node; and a charge sharing circuit positioned in the column of memory cells, the charge sharing circuit coupled to the high and low supply nodes, the charge sharing circuit operable to reduce direct-current (DC) power consumption.
