  • Patent number: 11342020
    Abstract: A variable resistive memory device includes a memory cell array and a control circuit block. The memory cell array includes a plurality of memory cells that are connected between a global word line and a global bit line. The control circuit block is positioned on at least one of edge portions of the memory cell array. The memory cell array is classified into a first group with the memory cells that are adjacent to the control circuit block and a second group with the memory cells that are remote in relation to the control circuit block. The second group is farther from the control circuit block than the first group. The control circuit block includes a write control unit that generates a control signal for writing on the memory cell in the first group in a different way compared to writing on the memory cell in the second group.
