METHOD OF OPERATING MEMORY DEVICE, MEMORY DEVICE USING THE SAME, AND MEMORY SYSTEM INCLUDING THE DEVICE

摘要

A memory device includes a control logic configured to control an overall operation of the memory device; a data storing unit configured to receive write data and write the write data according to control of the control logic and to output read data obtained by reading the write data; and a detector configured to repeatedly generate a comparison result based on the read data and a current determination result based on the comparison result and a previous determination result N times and to generate a final determination result according to a result of the repetition, where N is an integer of at least 2. The final determination result indicates whether an error has occurred and a type of the error.

1. A method of operating a memory device, the method comprising:
generating a current determination result based on a previous determination result and a comparison result generated based on read data read from a memory cell corresponding to a first address; storing the current determination result as the previous determination result; repeating the generating the current determination result and the storing the current determination result until the current determination result is generated N times, where N is an integer of at least 1; and generating a final determination result according to a result of the repetition, wherein the final determination result indicates whether the memory cell corresponding to the first address has an error and a type of the error.
