  • MEMORY SYSTEM AND INFORMATION PROCESSING SYSTEM
    Publication number: 20240061620
    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.

  • MEMORY SYSTEM
    Publication number: 20150095556
    Abstract: A memory system includes a first memory chip, a second memory chip, and a memory controller. The first memory chip and the second memory chip are connected to the memory controller via a plurality of data lines including a first data line and a second data line. The first memory chip is configured to outputs status information via the first data line to the memory controller. The second memory chip is configured to output status information via the second data line to the memory controller at the same time as the first memory chip.
