ABSTRACT:
In accordance with one embodiment of the invention, a memory device comprises an array of memory cells arranged into word lines and bit lines, with a sense amplifier and a plurality of reference cells for each bit line. The sense amplifier for a bit line compares the output of a memory cell for that bit line with the output of one of the plurality of reference cells for that bit line.
