PHASE CHANGE MEMORY GAPS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17528197 titled 'PHASE CHANGE MEMORY GAPS

Simplified Explanation

The abstract describes a patent application for a phase change memory (PCM) cell. The cell includes a first electrode, a heater/PCM portion made of a PCM material, a second electrode, and an electrical insulator stack surrounding the heater/PCM portion. The stack consists of alternating layers of different materials, creating gaps between the layers.

  • The patent application is for a PCM cell design.
  • The cell includes a first electrode, a heater/PCM portion, and a second electrode.
  • An electrical insulator stack surrounds the heater/PCM portion.
  • The stack is made up of alternating layers of different materials.
  • The layers create gaps between them.

Potential applications of this technology:

  • Memory devices: The PCM cell can be used in memory devices to store and retrieve data.
  • Computing systems: The technology can be integrated into computing systems to enhance memory performance.

Problems solved by this technology:

  • Heat management: The design includes a heater/PCM portion to efficiently manage heat in the cell.
  • Insulation: The electrical insulator stack provides insulation and protects the cell components.

Benefits of this technology:

  • Improved memory performance: The PCM cell design can enhance memory performance in various applications.
  • Efficient heat management: The heater/PCM portion helps in effectively managing heat within the cell.
  • Enhanced insulation: The electrical insulator stack provides insulation and protects the cell components.


Original Abstract Submitted

A PCM cell includes a first electrode, a heater/PCM portion electrically connected to first electrode, the heater/PCM portion comprising a PCM material, a second electrode electrically connected to the PCM material, and an electrical insulator stack surrounding the projection liner. The stack includes a plurality of first layers comprised of a first material and having a plurality of first inner sides facing towards the projection liner, and a plurality of second layers alternating with the plurality of first layers, the plurality of second layers comprised of a second material that is different from the first material, and the second plurality of layers having a plurality of second inner sides facing towards the projection liner. The plurality of second inner sides that are offset from the plurality of first inner sides forming a plurality of gaps.
