Abstract: PROBLEM TO BE SOLVED: To provide an MRAM assembly permitting to reduce an area necessary for line drive circuits by their effective arrangement and permitting space- saving design. SOLUTION: Word line drive circuits (6, 7) are assigned to two memory cell arrays (1, 2 or 2, 3) via each connecting node (4, 5) so that the drive circuit area is substantially reduced by half.
