Magnetic Random Access Memory Device and Sensing Method Thereof

摘要

A magnetic random access memory (MRAM) device includes sense lines, a selector, a reading circuit and a writing circuit. Each sense line is coupled to one or more MRAM cells. The selector is used to select one of the sense lines to allow a read or write operation. The reading circuit is coupled to the sense lines and provides a first sense current to the selected sense line during the read operation. The writing circuit is coupled to the sense lines and provides a second sense current to the selected sense line during the write operation.
