    摘要： A solid state, directly overwritable, electronic, non-volatile, high density, low cost, low energy, high speed, readily manufacturable, multibit single cell memory or control array based upon the novel switching characteristics provided by said unique class of semiconductor materials characterized by a large dynamic range of reversible Fermi level positions. The memory or control elements from which the array is fabricated exhibit orders of magnitude higher switching speeds at remarkably reduced energy levels. The novel memory elements of the instant invention are in turn characterized, inter alia, by numerous stable and non-volatile detectable configurations of local atomic and/or electrode order, which configurations can be selectively and repeatably accessed by electric input signals of yawing energy level. The memory elements are further characterized by enhanced stability, which stability is achieved through the use of compositional modulation of the semiconductor material from which the memory elements are fabricated.

    摘要： Disclosed herein is a solid state, directly overwritable, non-volatile, high density, low cost, low energy, high speed, readily manufacturable, single cell memory element having reduced switching current requirements and increased write/erase cycle life. The structurally modified memory element includes an electrical contact formed of amorphous silicon, either alone or in combination with a layer of amorphous carbon layer. The memory element exhibits orders of magnitude higher switching speeds at remarkably reduced switching energy levels. The novel memory elements of the instant invention are further characterized, inter alia, by at least two stable and non-volatile detectable configurations of local atomic and/or electronic order, which configurations can be selectively and repeatably accessed by electrical input signals of designated energies. The reduced switching current requirements and an increased write/erase cycle life are achieved by structurally modifying the electrical contact with the aforementioned layer of amorphous silicon.
