SYSTEM AND METHOD FOR SENSING DATA STORED IN A RESISTIVE MEMORY ELEMENT USING ONE BIT OF A DIGITAL COUNT

A method and system sense the logic state of an unknown initial data bit stored in a selected resistive memory cell. According to one method, a first count representing the logic state of the unknown initial data bit stored in the selected memory cell is generated. A second count is then generated, and represents a data bit having a first known logic state stored in the selected memory cell. A third count is then generated, and represents a data bit having a second known logic state stored in the selected memory cell. The logic state of the initial unknown data bit stored in the selected memory cell is then determined from the first, second, and third counts.
