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 GeSeAsor GeTeAs. 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).
