Abstract
The present invention is directed a method for programming multiple memory cells connected to a common word line to different resistance regimes. Each cell includes a bipolar switching memory element and an access transistor coupled in series between first and second conductive lines. The memory element and access transistor are disposed adjacent to the first and second conductive lines, respectively. The method includes the steps of applying a first voltage to the common word line to program a first group of memory cells to a first resistance regime; and after the first group of memory cells is programmed to the first resistance regime, programming a second group of memory cells to a second resistance regime by raising the potential of second conductive lines connected to the first group of memory cells to a second voltage and raising the first voltage of the common word line to a third voltage.
