Patent ID: 7266011

Claim:
A magnetic memory comprising: a plurality of common bit lines; and a plurality of memory cells, each memory cell including: at least one cell bit line being branched from a corresponding one of the common bit lines, functioning as a writing wire, and being disposed below the corresponding one of the common bit lines; at least one data storage portion, provided on at least an upper surface and side surfaces of an outer periphery of the cell bit line, which comprises a ferromagnetic material whose magnetization direction can be inverted by causing a current to flow in the cell bit line; at least one magneto-resistance effect element, disposed below the cell bit line, which comprises a magnetization free layer having a coercive force smaller than that of the ferromagnetic material of the data storage portion and senses the magnetization direction of the data storage portion; and a writing selection transistor which is connected at one of a source and a drain thereof to the cell bit line.
