Memory device and memory system including the same

A memory device, comprising:

• a non-volatile memory circuit including memory regions for storing memory hard repair data of memory banks and system regions for storing system hard repair data of the memory banks;
• a data bus suitable for transmitting the memory hard repair data and the system hard repair data during a boot-up operation, and transmitting soft repair data during a soft repair mode;
• registers suitable for storing data of a corresponding memory bank among the repair data transmitted through the data bus and activating when the transmitted repair data are stored;
• a control circuit suitable for selecting a register to store the transmitted repair data among the registers, and during the soft repair mode, deactivating a register that stores the same data as the transmitted repair data among the registers corresponding to a memory bank corresponding to the transmitted repair data;
• and
• memory banks suitable for performing a repair operation based on the data stored in activated registers.

A memory system, comprising:

• a memory device that comprises:
• a non-volatile memory circuit;
• memory banks,
• wherein the memory device programs system hard repair data inputted in a hard repair mode in the non-volatile memory circuit and performs a repair operation based on the repair data stored in the non-volatile memory circuit and soft repair data inputted in a soft repair mode;
• and
• a memory controller suitable for setting up the memory device in the hard repair mode or the soft repair mode, inputting the system hard repair data into the memory device in the hard repair mode, and inputting the soft repair data into the memory device in the soft repair mode.

A memory device, comprising:

• registers suitable for storing hard repair data and soft repair data, wherein each of the registers is activated when one of the hard repair data and the soft repair data is stored therein;
• a control circuit suitable for controlling the registers to store the hard repair data during a boot-up operation, and to store the soft repair data in a soft repair mode, wherein the control circuit in the soft repair mode deactivates one or more hard repair registers of the registers storing the hard repair data, which is the same as the soft repair data;
• and
• a memory bank suitable for performing a repair operation based on the hard repair data and the soft repair data stored in activated registers of the registers.
