Reverse program and erase cycling algorithms

摘要

Structures and methods for controlling operation of a programmable impedance element are disclosed herein. In one embodiment, a method of programming the programmable impedance element can include: (i) receiving a program command to be executed on the programmable impedance element; (ii) performing a program operation on the programmable impedance element in response to the program command; (iii) determining if the program operation successfully programmed the programmable impedance element; and (iv) performing an erase operation for programming the programmable impedance element in response to the program operation failing to successfully program the programmable impedance element.

1. A method of erasing a programmable impedance element, the method comprising:
a) receiving an erase command to be executed on the programmable impedance element; b) performing an erase operation on the programmable impedance element in response to the erase command; c) determining if the erase operation successfully erased the programmable impedance element; and d) performing a program operation for erasing the programmable impedance element in response to the erase operation failing to successfully erase the programmable impedance element.
