Abstract
A non-volatile latch circuit is provided. The non-volatile latch circuit includes a nanotube switching element capable of switching between resistance states and non-volatilely retaining the resistance state. The non-volatile latch circuit includes a volatile latch circuit is capable of receiving and volatilely storing a logic state. When the nanotube switching element is a resistance state, the volatile latch circuit retains a corresponding logic state and outputs that corresponding logic state at an output terminal. A non-volatile register file configuration circuit for use with a plurality of non-volatile register files is also provided. The non-volatile register file configuration circuit includes a selection circuitry and a plurality of nanotube fuse elements, each in electrical communication with one of a plurality of non-volatile register files. The selection circuitry is capable of applying electrical stimulus to each of the selected nanotube fuse elements to selectively bypass the corresponding register file.
