Abstract
A nonvolatile random access memory is formed by thin permalloy shaped into 'wiggle' patterns and magnetized to establish a plurality of memory cells arranged into an array. Magnetic domain walls are formed at apexes of the 'wiggle' pattern in each memory cell after a predetermined magnetic field is applied along the hard axis of the memory cell array by magnetization so aligned. Row address lines for reading and writing into the memory cells and column address lines for writing into the memory cells are provided to conduct currents through each column of the array for magnetoresistance readout.
