MAGNETIC RANDOM ACCESS MEMORY DEVICE AND DATA RECORDING METHOD

摘要

PURPOSE: A magnetic random access memory using a domain wall motion and current induction magnetic switching method is provided to improve integration by implementing the driving with only the write current of one direction. CONSTITUTION: A magnetic random access memory includes a switch structure(11), a data storing layer(13), a free layer(15), an intermediate electrode(12), an intermediate layer(14). The data storing layer is formed on the switch structure. The free layer is formed on the data storing layer. Two magnetic domains with difference magnetization direction or more are formed in the free layer. The intermediate electrode is formed between the switch structure and the data storing layer. The intermediate layer is formed between the data storing layer and the free layer.
