Read sensing circuit and method with equalization timing
A Magnetic Random Access Memory (MRAM) includes read sensing circuitry having an equalizer device configured between a bit cell output node and a reference node of the bit cell. The equalizer is turned on to couple the output node to the reference node during an initial portion of a read operation and to decouple the output node from the reference node after an equalization delay period. A sense amplifier is enabled to provide a data output from the bit cell only after the delay period and decoupling of the output node from the reference node to provide balanced sensing speed of data represented by parallel and antiparallel state magnetic tunnel junctions (MTJs).
