Patent ID: 7700985

Claim:
A multiferroic memory unit, comprising: a substrate having a source region and a drain region; an electrically insulating layer adjacent to the substrate; a control gate electrode adjacent to the electrically insulating layer and the source region and the drain region; and a data storage cell comprising a composite multiferroic layer, the data storage cell is at least partially between the insulating layer and the control gate electrode, and the composite multiferroic layer comprises at least one of, a ferromagnetic material in a matrix of a ferroelectric material, and a ferroelectric material in a matrix of a ferromagnetic material; and a second control sate electrode adjacent to the electrically insulating layer, the source region, and the drain region, and a second data storage cell comprising a second composite multiferroic layer, the second data storage cell separates the electrically insulating layer from the second control gate electrode, and the second data storage cell is separated from the data storage cell.
