  • Patent number: 10903272
    Abstract: A memory device may include a substrate having conductivity regions and a channel region. A first voltage line may be arranged over the channel region. A second voltage line, and third and fourth voltage lines may be electrically coupled to a first conductivity region and a second conductivity region respectively. Resistive units may be arranged between the third and fourth voltage lines and the second conductivity region. In use, changes in voltages applied between the second and third voltage lines, and between the second and fourth voltage lines may cause resistances of first and second resistive units to switch between lower and higher resistance values. The lower resistance value of the first resistive unit may be different from the lower resistance value of the second resistive unit and/or the higher resistance value of the first resistive unit may be different from the higher resistance value of the second resistive unit.
