Abstract
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.
