Patent ID: 7944735

Claim:
A method of making a memory cell comprising: providing an electronic memory element capable of storing a memory state, the electronic memory having cross-coupled first and second inverters wherein an input node of the first inverter is coupled to an output node of the second inverter and the input node of the second inverter is coupled to an output node of the first inverter; forming first and second nanotube switching elements capable of storing a memory state, the first and second nanotube switching elements disposed over the electronic memory element; electrically coupling the input node of the first inverter to the control structure of the first nanotube switching element and to the second conductive terminal of the second nanotube switching element and the first conductive terminal of the second nanotube switching element is coupled to a channel voltage line; and electrically coupling the input node of the second inverter to the control structure of the second nanotube switching element and to the second conductive terminal of the first nanotube switching element and the first conductive terminal of the first nanotube switching element is coupled to the channel voltage line.
