1. An apparatus comprising:
a sense amplifier coupled to a memory array and having a set of output terminals;
a latch coupled to a first output terminal of the sense amplifier, wherein the latch indicates a first memory state of a bit cell of the memory array at a first clock pulse and a second output terminal of the sense amplifier indicates a second memory state of the bit cell at a second, consecutive clock pulse; and
a comparator coupled to the latch and the second output terminal of the sense amplifier, wherein the comparator outputs:
a first output indicating a logic level of the memory state, and
a second output indicating whether the first memory state is equal to the second memory state.
