Abstract
Disturb from the reset to the set state may be reduced by creating an amorphous phase that is substantially free of crystal nuclei when programming the reset state in a phase change memory. In some embodiments, this can be achieved by using a current or a voltage to program that exceeds the threshold voltage of the phase change memory element, but does not exceed a safe current voltage which would cause a disturb.
