ABSTRACT:
The magnetic memory device comprises: a memory cell including two magnetoresistive effect elements serially connected to each other, and a select transistor connected to a connection node between the two magnetic resistant devices, a bit line connected to the connection node of the magnetoresistive effect elements via the select transistor, and a read circuit for reading information memorized in the magnetoresistive effect elements, based on a voltage of the connection node outputted to the bit line.
