Title:
LOGIC GATE CIRCUIT BASED ON MAGNETIC FIELD TRIGGERED SUPERLATTICE PHASE-CHANGE UNIT
Document Type and Number:
WIPO Patent Application WO/2017/161960
Kind Code:
A1
Abstract:
The present invention discloses a logic gate circuit based on a magnetic field triggered superlattice phase-change unit. The logic gate circuit comprises a magnetic field generation module, a superlattice phase-change module, a voltage divider resistor and a controllable switch element; a switch of a resistance state of the superlattice phase-change module is controlled by applying a pulsed magnetic field and a voltage pulse; the voltage divider resistor is connected to the superlattice phase-change module, and a connection point thereof acts as an output terminal of the logic gate circuit; the controllable switch element is disposed on a connection line between the superlattice phase-change module and the voltage divider resistor; by switching on the controllable switch element, logic writing is carried out by applying high-voltage or low-voltage pulse signals to the superlattice phase-change module; by switching off the controllable switch element, a logic operation result is read from an output terminal of the logic gate circuit; logic functions such as AND, OR, NOT, NOR, NAND, XNOR, XOR, implication, inverse implication, multi-terminal AND, multi-terminal NAND, multi-terminal OR, and multi-terminal NOR can be achieved; the circuit structure is simple and achieves a range of logic functions, and the circuit is simple in structure, low in power consumption and non-volatile.
