  • Publication number: 20100061141
    Abstract: A non-volatile memory device may include a plurality of data cells, each data cell of the plurality of data cells programmed to have a first resistance variation among a plurality of first resistance variations; and a plurality of reference cells, each reference cell of the plurality of reference cells programmed to have a second resistance variation among a plurality of second resistance variations. A change in a resistance of the data cells is used to identify a level of data programmed to memory. Because the resistance variation of the data cells may change with time or due to changes in temperature, a reference cell is also included in the non-volatile memory device. The reference cell is used for effective reading of the data value of a corresponding data cell. A storage system may include the non-volatile memory device.
