  • Publication number: 20210182144
    Abstract: The present technology relates to a memory device, a memory system including the same, and a method of operating the memory system. The memory device includes a cam block including a plurality of pages, peripheral circuits configured to read a cam data of a page unit that is stored in a selected page among the plurality of pages of the cam block during a cam data read operation, a cam data read controller configured to receive the read cam data of the page unit from the peripheral circuits during a cam data load operation and configured to output the received cam data of the page unit as output cam data, and a control logic configured to control the peripheral circuits to perform the cam data read operation and the cam data load operation. The cam data read controller stops the cam data load operation based on a check data that is included in the read cam data of the page unit.
