Abstract
A nonvolatile random access memory array is formed by permalloy thin films patterned into 'wiggle' shapes. Address lines for reading and/or writing into the memory cells are operatively connected to associated circuitry such that writing at a selected location in the array is accomplished using coincident currents. Each memory cell in the array is arranged for passage of column conducted current to effect magnetoresistance readout in conjunction with row address lines and the aforementioned associated circuitry.
