| 1. A method for operating an integrated circuit memory array, said memory array comprising a cross-point array of passive
element memory cells, each coupled between an associated word line and an associated bit line, said method comprising:
in a first mode of operation, biasing selected word lines at a lower voltage than unselected word lines, and biasing selected
bit lines at a higher voltage than unselected bit lines; and
in a second mode of operation, biasing selected word lines at a higher voltage than unselected word lines, and biasing selected
bit lines at a lower voltage than unselected bit lines.
