Patent ID: 10290348

Abstract:
Systems and methods for providing a one-time programmable chalcogenide-based memory with improved memory cell IV characteristics are described. The memory cells of the one-time programmable chalcogenide-based memory may include a chalcogenide-based material. The chalcogenide-based material may comprise a germanium-antimony-tellurium compound (GST), a chalcogenide glass, or a chalcogenide alloy such as Ge10Se54As36 or Ge17Te50As33. The chalcogenide-based memory may be written as a one-time programmable memory in which forming operations are performed on only memory cells that are to be programmed to store a first binary value (e.g., binary “1” data values) and not performed on other memory cells that are to store a second binary value different from the first binary value (e.g., binary “0” data values).
