摘要: A multilevel phase change memory cell may have a plurality of intermediate levels between a set and a reset or a crystalline and amorphous states. These intermediate levels between set and reset may be differentiated not only by programming current, but also by different programming pulse widths. As a result, the intermediate states may be positioned, on the programming current versus programming pulse width curve, in regions of common resistance with a relatively large range of programming current.

摘要: 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.

摘要: A phase change memory may be formed with an insulator made up of two different layers having significantly different thermal conductivities. Pores may be formed within the stack of insulating layers and the pores may be filled with heaters, chalcogenide layers, and electrodes in some embodiments. The use of the two different insulator layers enables embodiments where thermal losses may be reduced and an amorphous region may be maintained along the entire length of the phase change material layer.
