Abstract
Operational information read out by a read-out sense amplifier () is transferred via the data line DB to a volatile memory section. The volatile memory section is configured with the volatile memory section () having a SRAM configuration and the second volatile memory section () configured with latch circuits, both sections respectively connected in parallel with the data line DB. The operational information, which may be provided depending on an operation state of the write-protect information and other information stored in the non-volatile memory cell MC selected by the word line WLWP, is written and read out with respect to the first volatile memory section () in response to the identification information linked with the operational information. The operational information which must be constantly accessible, is written into the second volatile memory section (). Thus, the operational information is available in response to attributes of the operational information.
