Title:
NONVOLATILE LOGIC CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2020/137341
Kind Code:
A1
Abstract:
Provided is a nonvolatile logic circuit that uses the non-complementarity of a pair of variable-resistance memory elements to achieve enhanced functionality without an increase in circuit scale. A nonvolatile logic circuit (10) that comprises: a memory part (12) that has a pair of variable-resistance memory elements (a pair of MTJ elements) (M1 and M2); a computation part (11) that is connected to the memory part (12) and performs a computation that is based on input signals (in1 and in2) and logic values that correspond to the resistances of the pair of MTJ elements (M1 and M2); a determination circuit (3) that determines whether the resistances of the pair of MTJ elements (M1 and M2) are complementary or non-complementary; and an output circuit (2) that is connected to the computation part (11) and the determination circuit (3) and outputs signals (out1 and out2) that correspond to the results of the computation performed by the computation part (11) or signals (out1 and out2) that correspond to the results of the determination made by the determination circuit (3).
