Abstract:
1. A thin film magnetic memory device, comprising: a memory array having a plurality of memory cells for magnetic data storage arranged therein, each memory cell including a magnetic storage portion having an electric resistance varying according to a magnetization direction that is rewritable by application of a prescribed magnetic field; a peripheral circuitry provided in a region adjacent to said memory array, for conducting data read operation and data write operation from and to said memory array; and first and second power supply lines for supplying an operating voltage to said peripheral circuitry, wherein said first and second power supply lines are arranged so that a first magnetic field generated by a current flowing through said first power supply line and a second magnetic field generated by a current flowing through said second power supply line are applied to said memory array in an easy-axis direction of said magnetic storage portions.
