Abstract
An apparatus comprising a latch circuit, a non-volatile storage circuit, and a switching circuit. The latch circuit may be configured to be dynamically programmable. The non-volatile storage circuit may be configured to be re-programmable. The switching circuit may be configured to transfer data from (i) the non-volatile memory element into the latch circuit in response to a first control signal and (ii) the latch circuit into the non-volatile memory circuit in response to a second control signal.
Claims20
An apparatus comprising:
- a latch circuit;
- and
- a non-volatile storage circuit, wherein data is transferred from (i) said non-volatile storage circuit into said latch circuit in response to a first control signal and (ii) said latch circuit into said non-volatile storage circuit in response to a second control signal.
An apparatus for storing and retrieving data comprising:
- means for transferring data from a non-volatile storage circuit into a latch circuit in response to a first control signal;
- and
- means for transferring data from said latch circuit into said non-volatile storage circuit in response to a second control signal.
A method of storing and retrieving data comprising the steps of:
- (A) transferring data from a non-volatile storage element into a latch circuit in response to a first control signal;
- and
- (B) transferring data from said latch circuit into said non-volatile storage circuit in response to a second control signal.
