Abstract

See full text

A semiconductor storage device includes a non-volatile first memory, a second memory that includes a first area for recording data to be recorded in the first memory and a second area for recording data read from the first memory, and a memory controller that controls the first memory. The memory controller acquires event logs for each event, adds a footer that specifies the data start position of the event log to an end of each of the event logs, sequentially records the event logs to which the footer is added in an order of occurrence of the event from a low address toward a high address of the first area, stores a plurality of the event logs which are recorded in the first area and has the footer added to the plurality of the event logs in the first memory, and sequentially reads the plurality of event logs stored in the first memory in an order from a latest event log, based on content of the footer added to each event log, to sequentially record the read event logs from a low address toward a high address of the second area in a read order of the read event logs.
