Abstract:
1. A magnetic memory device, comprising: a plurality of memory cells each including one magnetoresistive effect revealing body and arranged side by side along a pair of write lines; a plurality of auxiliary write lines arranged so that each memory cell is provided with one auxiliary write line, each auxiliary write line being connected to the pair of write lines to introduce write currents flowing through the pair of write lines to a vicinity of the magnetoresistive effect revealing body; and transistors arranged so that one transistor is inserted in each auxiliary write line, to allow the write currents to flow bidirectionally through the auxiliary write lines in an operating state of the transistors, wherein the transistors are each composed of a multi-emitter type bipolar transistor including first and second emitter terminals, each transistor being configured such that a collector terminal and the first emitter terminal are connected to the respective auxiliary write lines, and the second emitter terminal is connected to the magnetoresistive effect revealing body.
