Abstract
An integrated circuit includes an array of resistance changing memory cells and a first circuit. The first circuit is configured to set a selected memory cell to a crystalline state by applying a decreasing stair step pulse to the selected memory cell. The pulse is based on a reset current distribution for the array of memory cells.
