Abstract:
A method for accessing a phase change memory device, wherein a first sub-plurality of bitlines is grouped in a first group and a second sub-plurality of bitlines is grouped in a second group. At least a bitline in the first and second groups are selected; currents are supplied to the selected bitlines; and a selected wordline is biased. The bitlines are selected by selecting a first bitline in the first group and, while the first bitline is selected, selecting a second bitline in the second group which is arranged on the selected wordline symmetrically to the first bitline in the first group.
