Title of Invention	ELECTRICALLY ERASABLE PHASE CHANGE MEMORY DEVICE
Abstract	An electrically erasable phase change memory device comprising atleast one pore of phase change material which is capable of being reversibly electrically switched between .t least two electrically detectable states, electrical contact means making electrical contact with at least two portions of said pore to establish an electrical path through said pore between the points of contact with said at least two portions; and means for applying electrical signals to said electrical contact means to Cause reversible switching of at least a volume portion of said phase change material in said electrical path in saj.d pore between said at least two detectable states, said first detectable state being characterized by an electrical conductivity which is lower than that of said second detectable state.
