  • MEMORY DEVICE, FAILURE BITS DETECTOR AND FAILURE BITS DETECTION METHOD THEREOF
    Publication number: 20240120018
    Abstract: A memory device, a failure bits detector, and a failure bits detection method thereof are provided. The failure bits detector includes a current generator, a current mirror, and a comparator. The current generator generates a first current according to a reference code. The current mirror mirrors the first current to generate a second current at a second end of the current mirror. The comparator compares a first voltage at a first input end with a second voltage at a second input end to generate a detection result.
