Memory Program Sequence Timing Checks for Abnormal Write Detection

The memory device performs self-diagnosis by automatically detecting abnormal program sequences through internal timing verification. The device compares actual program execution time against expected time ranges and identifies errors without external intervention, enabling the system to protect itself and eliminating the need for time-consuming manual debugging by firmware teams

The detector implements a feedback mechanism by continuously monitoring program sequence execution and comparing actual timing against predefined expectations. When deviations are detected, the system generates error indicators that trigger automatic error handling mechanisms, creating a closed-loop system that continuously verifies and corrects program execution without manual intervention

The detector is designed as a multi-functional component that performs multiple tasks: timing verification, error detection, error classification, and triggering appropriate error handling mechanisms. By consolidating these functions into a single universal detector module, the patent avoids the need for separate complex systems for each function, thereby reducing overall device complexity while maintaining comprehensive error detection capabilities

The detector acts as an intermediary component between the program execution unit and the error handling mechanisms. It monitors program sequences and translates timing deviations into standardized error indicators that can be processed by existing error handling infrastructure, thereby bridging the gap without requiring complete system redesign and minimizing added complexity
