ABSTRACT:
An apparatus for determining the state of a multistate memory cell. The apparatus includes three sense amplifiers, each with an associated reference cell which produces a reference voltage for input to each of the sense amplifiers. The apparatus includes circuitry which allows the reference cell currents to be varied to produce the reference voltages or pairs of reference voltages needed to accurately determine the threshold voltage and hence state of a programmed or erased memory cell.
