  • Patent number: 12277348
    Abstract: A memory system includes a non-volatile memory and a controller that includes a first memory and is configured to write log data to the first memory, including a history of commands for controlling the memory system. An information processing system includes the memory system and an information processing device configured to store an expected value and to transmit a signal that instructs the memory system to stop when a value of the log data transmitted from the memory system does not match the expected value. The expected value and the transmitted value are determined based on the log data of the memory system.
