Abstract
An output memory circuit device for and method of providing protection to an integrity of data stored in an external memory circuits during an output operation utilizing the data. Control means selectively controls activation of an external memory to an active state and an inactive back-up state, and obtains data from the external memory circuit during times corresponding to the active state. Storage circuit receives and temporarily stores data supplied by the control circuit and processing circuit receives and processes data fed from the storage circuit and outputs processed data to an output circuit. The control circuit selectively controls an activation of the external memory circuit to the inactive back-up state during times when receiving and processing is conducted to receive and process data fed from the storage circuit and output processed data to the output circuit.
