Subject matter disclosed herein relates to memory devices and, more particularly, to programming a memory cell.

主权项

1. A method of programming a first memory cell and a second memory cell, each of the first memory cell and the second memory cell having at least a first stable state and a second stable state, the method comprising:
applying a decreasing current programming signal to the first memory cell for programming the first memory cell to one of the first and second stable states of the first memory cell; applying a decreasing voltage programming signal to the second memory cell for programming the second memory cell to one of the first and second stable states of the second memory cell; and detecting whether the decreasing current programming signal is less than a current threshold value or whether the decreasing voltage programming signal is less than a voltage threshold value.
