Memory device, a controller for controlling the same, a memory system including the same, and an operating method of the same

An operating method of a memory device, the operating method comprising:

• receiving error check and scrub (ECS) mode information from a controller;
• receiving a page offline address from the controller;
• performing a scrubbing operation in response to the ECS mode information;
• and
• reporting an error address detected in the scrubbing operation to the controller,
• wherein the page offline address is excluded from error addresses detected in the scrubbing operation and the scrubbing operation is performed after excluding a range corresponding to the page offline address.

A memory system, comprising:

• a memory device;
• and
• a controller configured to control the memory device, to receive an error address from the memory device, and to transmit a mapped-out page offline address to the memory device,
• wherein the memory device includes a memory cell array, an error correction circuit configured to read data from the memory cell array and to correct an error in the read data, and an error check and scrub (ECS) circuit including a first register, configured to perform a scrubbing operation on the memory cell array and to store an error address detected in the scrubbing operation, and a second register configured to store the page offline address from the controller.
