MEMORY SYSTEM AND DATA PROTECTION METHOD THEREOF

摘要

A memory system includes an abnormality detecting block including a plurality of abnormality detectors to detect whether an abnormal condition has occurred during a normal operation due to an external attack. An abnormality processing block is configured to process the abnormal condition in hardware, and a central processing unit is configured to execute a first process to detect whether the abnormal condition has occurred during the normal operation and to execute a second process to process the abnormal condition in software. A monitoring unit is configured to monitor an operation of the second process and to determine whether an error has occurred in the second process based on a monitoring result.
