Abstract
New types of memory cell structures (20, 40) for a magnetic random access memory are provided. A memory cell (20, 40) has a plurality of cell pieces (21-24) where digital information is stored. Each cell piece is formed by magnetic layers (27, 28) separated by a conductor layer (29). A word line (25, 41) is placed adjacent each cell piece for winding around cell pieces (21-24) and meandering on a same plane on cell pieces (21-24), for example. The invention attains less power consumption and effective usage for a word current.
