Magnetic memory and method for using the same

Abstract

The present invention is directed to a memory circuitry that includes a magnetic memory element and a selector coupled in series between a first conductive line and a second conductive line; a current detector coupled to the second conductive line; and a means for supplying a sufficiently high voltage to the first conductive line for turning on the selector. When the selector turns on, the current detector detects a current flowing across the selector and effectuates a current limiter to reduce the current while maintaining the selector on. The memory circuitry may be operated by applying a sufficiently high voltage to the first conductive line for turning on the selector; reducing a current flowing through the selector while maintaining the sufficiently high voltage on the first conductive line; and determining a resistance state of the magnetic memory element.
