ABSTRACT:
A method and apparatus for reading a magnetoresistive memory is disclosed wherein the wordline current is turned off during selected sensing operations. This substantially eliminates the noise that is typically injected by the wordline current into the bit structures during the sensing operations, which increases the signal-to-noise ratio on the sense lines. This, in turn, significantly increases the speed of the sensing operations and thus the read access time of the memory. Substantial power savings are also realized.
