Abstract: A memory module includes a first memory device that includes first circuit nodes for communication with a memory controller and second circuit nodes for communication inside the memory module, a second memory device that includes first circuit nodes for communication with the memory controller and second circuit nodes for communication inside the memory module, and an internal data bus that couples the first memory device to the second memory device to carry data between the second circuit nodes of the first memory device and the second circuit nodes of the second memory device. When an internal read command is applied to the first memory device and an internal write command is applied to the second memory device, data is transferred from the first memory device to the second memory device through the internal data bus.

Abstract: A memory system includes a memory device including a plurality of memory blocks, a first detection block suitable for detecting a hot memory block based on a number of times that a write operation is performed among the memory blocks during the write operation, a second detection block suitable for detecting first memory blocks based on the number of times that the write operation is performed among the memory blocks and detecting a cold memory block based on addresses of the first memory blocks, when the hot memory block is detected, and a wear-leveling block suitable for swapping data of the hot memory block for data of the cold memory block.

Abstract: A memory system includes a memory device and a memory controller. The memory device has a plurality of memory regions. The memory controller is configured to generate a read command for a first memory region corresponding to one of the plurality of memory regions when the number of write commands successively generated for the first memory region reaches a reference value.

Abstract: A method for operating a memory system includes: reading a data from a memory device; detecting and correcting an error of the data; when the error of the data is equal to or greater than a threshold value, deciding an address corresponding to memory cells from which the data is read in the memory device as a rewrite-requiring address; and rewriting the data of the memory cell corresponding to the rewrite-requiring address.
