Abstract:
1. A magnetic random access memory comprising: bit lines extending in a first direction; write word lines extending in a second direction perpendicular to the first direction; a common driver line extending in the second direction; first switches each connected between one end of each of said bit lines and said common driver line; a first write bit line driver/sinker which is connected to said common driver line, supplies a write current to one of said bit lines, and absorbs the write current from one of said bit lines; a common data line extending in the second direction; second switches each connected between the other end of each of said bit lines and said common data line; a second write bit line driver/sinker which is connected to said common data line, supplies the write current to one of said bit lines, and absorbs the write current from one of said bit lines; and a read circuit which is connected to said common data line and supplies a read current to one of said bit lines.
