Abstract
An apparatus and method for storing data in a semiconductor memory. In accordance with some embodiments, the semiconductor memory has a continuous storage layer of soft ferromagnetic material having opposing top and bottom surfaces with overall length and width dimensions and an overall thickness dimension between the opposing top and bottom surfaces. A plurality of spaced apart, discrete reference layers are adjacent a selected one of the opposing top or bottom surfaces of the continuous storage layer with each having a fixed magnetic orientation. A plurality of spaced apart, discrete barrier layers are disposed in contacting relation between the discrete reference layers and the continuous storage layer.
