Abstract
A method includes sampling magnetic bits, applying a write current pulse to the magnetic bits to set them to a first logic state, resampling the magnetic bits, and comparing the results of sampling and resampling to determine the bit state for each magnetic bit. A read or write operation may be received after initiation of writing back magnetic bits having the second state, where the write-back can be aborted for a portion of the bits in the case of a write operation. The write-back may be performed such that different portions of the magnetic bits are written back at different times, thereby staggering the write-back current pulses in time. An offset current may also be used during resampling.
