  • Patent number: 11978511
    Abstract: A phase-change memory (PCM) cell is provided to include a first electrode, a second electrode, and a phase-change feature disposed between the first electrode and the second electrode. The phase-change feature is configured to change its data state based on a write operation performed on the PCM cell. The write operation includes a reset stage and a set stage. In the reset stage, a plurality of reset current pulses are applied to the PCM cell, and the reset current pulses have increasing current amplitudes. In the set stage, a plurality of set current pulses are applied to the PCM cell, and the set current pulses exhibit an increasing trend in current amplitude. The current amplitudes of the set current pulses are smaller than those of the reset current pulses.

  • Patent number: 11972826
    Abstract: Disclosed herein are related to a system and a method of extending a lifetime of a memory cell. In one aspect, a memory controller applies a first pulse having a first amplitude to the memory cell to write input data to the memory cell. In one aspect, the memory controller applies a second pulse having a second amplitude larger than the first amplitude to the memory cell to extend a lifetime of the memory cell. The memory cell may include a resistive memory device or a phase change random access memory device. In one aspect, the memory controller applies the second pulse to the memory cell to repair the memory cell in response to determining that the memory cell has failed. In one aspect, the memory controller periodically applies the second pulse to the memory cell to extend the lifetime of the memory cell before the memory cell fails.

  • Patent number: 10475742
    Abstract: A method of forming a semiconductor device structure includes: forming a first conductive structure over a substrate, the first conductive structure including twin boundaries; and wherein the forming the first conductive structure includes manipulating process conditions so as to promote formation of the twin boundaries resulting in a promoted density of twin boundaries such that the first conductive structure has an increased failure current density (FCD) relative to a baseline FCD of an otherwise substantially corresponding second conductive structure which has an unpromoted density of twin boundaries, the unpromoted density being less than the promoted density and such that the first conductive structure has a resistance which is substantially the same as the second conductive structure.
