Abstract
An MRAM device has a new type of memory bank (,) that includes bit lines (,), a reference line (,) and digit lines (,), on intersections of bit lines and digit lines a plurality of magnetic memory cells (,) are arrayed. Bit lines are formed on both sides of the reference line on a substrate. Since each bit line is fabricated closely to the reference line, each cell has substantially the same hysteresis characteristics, which allow the MRAM device to provide a steady operation mode.
