Abstract: A method is provided for using a multi-level cell memory device. The method includes writing first data to a first portion of a memory array using a first number of state levels for memory cells of the first portion of the memory array. The method further includes re-writing second data to a second portion of the memory array using a second number of state levels for memory cells of the second portion of the memory array. The second number is different from the first number.

Abstract: A substantially planar heater for a phase change memory may taper as it extends upwardly to contact a chalcogenide layer. As a result, the contact area between heater and chalcogenide is reduced. This reduced contact area can reduce power consumption in some embodiments.
