Document Type and Number:
Japanese Patent JP4229607
Kind Code:
B2
Abstract:
In data write operation, a data write current starts being supplied to a write word line of the selected row at a first time without waiting for redundant determination. A data write current starts being supplied to a bit line or sub bit line of the selected column at a second time that is later than the first time according to the redundant determination result. The redundant determination is conducted between the first and second times. The data write currents flowing through the write word line and the bit line generate magnetic fields of the hard-axis and easy-axis directions for the selected memory sell, respectively.
