    Abstract: A ReRAM memory array includes ReRAM memory cells and a select circuit having first and second series-connected select transistors connected in series with a ReRAM device. When ReRAM memory cell(s) are selected for programming, the bit line coupled to the ReRAM memory cell(s) to be programmed is biased at a first voltage potential and the source line coupled to the ReRAM memory cell(s) to be programmed is biased at a second voltage potential less than the first voltage potential, the difference between the first voltage potential and the second voltage potential being sufficient to program the ReRAM device. The gates of first and second series-connected select transistors of ReRAM memory cell(s) to be programmed are supplied with positive voltage pulses. The gates of second series-connected select transistors of respective ReRAM memory cell(s) unselected for programming are supplied with a voltage potential insufficient to turn them on.

  • Patent number: 12154622
    Abstract: A ReRAM memory array includes ReRAM memory cells having two series-connected select transistors connected in series with a ReRAM device. When ReRAM memory cell(s) are selected for erasing, the bit line coupled to the ReRAM memory cell(s) to be erased is biased at a first voltage potential. The source line coupled to the ReRAM memory cell(s) to be erased is biased at a second voltage potential greater than the first voltage potential, the difference between the first voltage potential and the second voltage potential being sufficient to erase the ReRAM device. The gates of the series-connected select transistors of the ReRAM memory cell(s) to be erased are supplied with positive voltage pulses. The gates of the series-connected select transistors of the ReRAM memory cell(s) unselected for erasing are supplied with a voltage potential insufficient to turn them on.
