Abstract
A magnetic memory device includes a first interconnect, a second interconnect, a memory cell, and a write circuit. The memory cell is electrically coupled between the first interconnect and the second interconnect, and includes a variable resistance element and a switching element. The write circuit supplies a write voltage from the current source circuit or the voltage source circuit to write data into the memory cell. The write circuit supplies the write voltage to one of the first interconnect and the second interconnect using the voltage source circuit during a first period ranging from a first time to a second time. The write circuit supplies the write voltage to one of the first interconnect and the second interconnect using the current source circuit during a second period ranging from a third time to a fourth time.
