Patent ID: 10579759

Abstract:
An apparatus for modeling a resistive memory device may include a first model circuit and a second model circuit. The first model circuit may include a current-voltage characteristic-embodying circuit, a phase-expressing circuit, and a characteristic-expressing circuit. The current-voltage characteristic-embodying circuit may generate current-voltage characteristic data of the resistive memory device. The phase-expressing circuit may generate phase-expressing data for changing phases of the resistive memory device. The characteristic-expressing circuit may be configured to generate characteristic-expressing data for identifying resistance variation characteristics of the resistive memory device. The characteristic-expressing circuit may transmit the characteristic-expressing data to the current-voltage characteristic-embodying circuit. The second model circuit may include a state-maintaining circuit with a resistive memory device model. The state-maintaining circuit may determine data storage phase in response to the phase-expressing data. The second model circuit may transmit a voltage signal of the state-maintaining circuit to the current-voltage characteristic-embodying circuit.
