Abstract

A write voltage generator is connected with a magnetoresistive random access memory. The write voltage generator provides a write voltage during a write operation. A storage state of a selected memory cell in a write path of the magnetoresistive random access memory is changed in response to the write voltage. The write voltage generator includes a temperature compensation circuit and a process corner compensation circuit. The temperature compensation circuit generates a transition voltage according to an ambient temperature. The transition voltage decreases with the increasing ambient temperature. The process corner compensation circuit receives the transition voltage and generates the write voltage.
