Resistive random access memory, and method for manufacturing resistive random access memory
Abstract:
A resistive random access memory includes a memory cell including a resistive element having a resistance which varies according to a write operation and stores data according to the resistance of the resistive element, a reference resistive element having a resistance set to a first value, a voltage line set to a first voltage during a first write operation in which the resistance of the resistive element is varied from a second value higher than the first value to the first value, and a voltage control circuit arranged between first ends of the two resistive elements. The voltage control circuit adjusts a value of the first voltage supplied from the voltage line so as to reduce a difference between currents flowing through the two resistive elements during the first write operation, and supply the adjusted first voltage to the first ends of the two resistive elements.
