摘要: A method and a feedback controller for programming at least one multi-level phase-change memory cell with a programming signal. The method and feedback controller include a sequence of write pulses applied to the multi-level phase change memory cell, wherein the feedback controller adjusts in real time at least one parameter of each write pulse as a function of a determined resistance error of the phase-change memory cell with respect to a desired reference resistance level.
