Abstract
A sense amplifier detecting a small current differential between a selected memory cell and a reference cell in a memory array includes a first pass transistor, a second pass transistor, a cross-coupled transistor arrangement and a differential amplifier. The cross-coupled transistor arrangement detect a small current differential between a bit sense current line and a bit sense reference current line. The difference current is amplified by the differential amplifier to produce an output data voltage indicative of the binary state of the selected memory cell.
