ABSTRACT:
A multiconfigurable integrated circuit having volatile and nonvolatile segments configured and interconnected so that data can be nonvolatilely entered and transferred at high frequency in the volatile segment, so that formerly entered data can be nonvolatilely stored while new data is entered and volatiley utilized, and so that previously stored nonvolatile data can be recalled and volatilely utilized. In one form, the circuit is comprised of a shift register stage selectively connectable to a nonvolatile memory cell structure. Interconnection of multiple circuits and the addition of analog switches creates electronic equivalents of DIP switches and various other multiple pole selectively controlled switching configurations.
