Abstract
A non-volatile random access memory is described incorporating a plurality of memory cells, each memory cell having a Hall effect device including amorphous magnetic material and a switch for directing current through the flail effect device. An array of memory cells are interconnected by word lines, current lines, and bit lines. The invention overcomes the problem of a rugged non-volatile random access memory with long term reliability.
