Abstract

Sensing circuitry including a sense amplifier 400 for latching a bit of data on a true bit line and a complementary bit of data on a complementary bit line. Circuitry 403, 404, 405 is included for performing boolean operations on bit of data latched in sense amplifier 400 in response to a bit of modifying data. Circuitry 403, 404, 405 during an AND operation pulls down the true bit line when the bit of modifying data a logic 0.
