Abstract: The present invention seeks to reduce the amount of current required for a write operation by using a process for forming the read conductor within a recessed write conductor, the write conductor itself formed within a trench of an insulating layer. The present invention protects the MTJ from the voltages created by the write conductor by isolating the write conductor and enabling the reduction of current necessary to write a bit of information.

Abstract translation: 本发明试图通过使用在凹形写入导体内形成读取导体的工艺来减少写入操作所需的电流量，该写入导体本身形成在绝缘层的沟槽内。 本发明通过隔离写入导体并且使得能够减少写入一位信息所需的电流来保护MTJ免受由写入导体产生的电压的影响。
