  • Patent number: 11659720
    Abstract: A resistive random-access memory (ReRAM) array is provided. The ReRAM array includes a silicon over insulator (SOI) substrate; a first bit line; a first inverted bit line of the first bit line; a second bit line; a second inverted bit line of the second bit line; a first word line; a first inverted word line of the first word line; a first ReRAM cell comprising a first MOSFET, a second MOSFET, and a resistive element; and a second ReRAM cell comprising a first MOSFET, a second MOSFET, and a resistive element connected in series; wherein upon applying a predefined potential on elements of the first ReRAM cell, a state of the first ReRAM cell is adjusted without effecting a state of the second ReRAM.

  • Publication number: 20230096127
    Abstract: A resistive random-access memory (ReRAM) cell includes a field-effect transistor (FET) and a resistive element. The FET having a gate port, a drain port, and a source port. The gate port is connected to a word-line (WL) of the ReRAM cell, the source port is connected to a bit-line (BL) of the ReRAM cell, and a first port of the resistive element is connected to the drain of the FET. A second port of the resistive element is connected to a source-line (SL) of the ReRAM cell. During reset operation SL is connected to a high-voltage and BL to a low-voltage. During set operation SL is connected to a low-voltage and BL to a high-voltage. Using this common source configuration overcomes the requirement for a wider FET width of the prior art so as to accommodate the current supply needed during reset operation, and avoids overstressing of the FET.
