Abstract:
1. A method of operation of a spin-torque magnetoresistive memory, the method comprising: sampling magnetic bits to provide a sampled voltage for each of the magnetic bits, wherein the magnetic bits correspond to a page within the spin-torque magnetoresistive memory; applying a first write current pulse to each of the magnetic bits to set all of the magnetic bits in the page to a first logic state; resampling each of the magnetic bits in the page to provide a resampled voltage for each magnetic bit; for each magnetic bit in the page, comparing the resampled voltage with the sampled voltage to determine a bit state for the magnetic bit, wherein the bit state for each magnetic bit is either the first logic state or a second logic state; inverting all the bit states for the magnetic bits in the page when a majority of the magnetic bits are in the second logic state; and initiating a write-back to each of the magnetic bits in the page having the second logic state, wherein the write-back includes applying a second write current pulse having opposite polarity in comparison with the first write current pulse to set the magnetic bit in the spin-torque magnetoresistive memory to the second state.
