MRAM Cells and Circuit for Programming the Same

摘要

A circuit includes magneto-resistive random access memory (MRAM) cell and a control circuit. The control circuit is electrically coupled to the MRAM cell, and includes a current source configured to provide a first writing pulse to write a value into the MRAM cell, and a read circuit configured to measure a status of the MRAM cell. The control circuit is further configured to verify whether a successful writing is achieved through the first writing pulse.
