Abstract
A magnetic memory device including a plurality of word lines, a plurality of bit lines which intersect the word lines and are put into groups, a plurality of memory cells which are arranged at intersections between the bit lines and the word lines, each memory cell including a magnetic element and a transistor which are connected in series, a first decoder which sequentially selects the word lines, a second decoder which sequentially drives the bit lines of each group, a weighting adder which performs weighting addition of currents flowing on bit lines in a selected group to generate an added current signal, a current/voltage converter which converts the added current signal into a voltage signal, and an analog-to-digital converter which digitizes the voltage signal.
