Apparatus, system and method to reduce a read voltage across a memory cell and improve read sense margin

Abstract:

A method, apparatus and system. The method includes: generating, during a read operation of a memory cell, a mirror current iMir1 at one of a WL node or a BL node of the memory cell opposite, respectively, one of a BL side or a WL side of the memory cell to which a current mode sense circuitry is connected, the iMir1 to reduce a value of the read voltage from VDM1 to VDM2, wherein the read voltage is between the WL node and the BL node; and sensing, using the current mode sense circuitry, a logic state of the memory cell at VDM2.
