Abstract
A memory cell includes a volatile circuit operable to store first data, and a nonvolatile circuit coupled to the volatile circuit and operable to store second data. The volatile circuit is operable to program the nonvolatile circuit with the first data, and the nonvolatile circuit is operable to program the volatile circuit with the second data.
Claims23
A non-volatile latch circuit, comprising:
- a first, volatile information-storage element;
- a second, non-volatile information-storage element electrically programmable, associated with the first information-storage element;
- first circuit means activatable for operatively coupling the second information-storage element to the first information-storage element, the first circuit means being activated for loading into the first information-storage element an information stored in the second information-storage element,
- second circuit means associated with the first information-storage element for programming the first information-storage element in a select state;
- third circuit means associated with the second information-storage element and driven by the first information-storage element for selectively enabling the programming of the second information-storage element depending on the state of the first information-storage element.
