Crossbar Assigned Patent

Crossbar, Inc., Santa Clara, CA, has been assigned a patent (12437811) developed by Li; Zhi, Santa Clara, CA, Jo; Sung Hyun, Sunnyvale, CA, and Frick; Jordan, San Jose, CA, for an “erase algorithm with a weak program pulse for non-volatile memory.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Improved erase techniques and apparatuses can improve performance and longevity of non-volatile memory. Various disclosed techniques include performing an erase operation(s) on a group of such memory cells, followed by a weak program operation. One or more subsequent erase-verify operations can be implemented until no erase disturb states are detected for the memory cells, or until a maximum erase-verify cycle count is reached. In one or more embodiments, additional weak program and erase-verify cycles can be implemented to enhance cycle longevity and reduce erase disturb states for the group of non-volatile memory.”

The patent application was filed on 2023-03-08 (18/119104).
