Abstract: An operating method of a memory device, which includes a first memory region and a second memory region, includes reading first data from the first memory region and storing the read first data in a data buffer block, performing a first XOR operation on the first data provided from the data buffer block and second data read from the second memory region to generate first result data, writing the first data stored in the data buffer block in the second memory region, performing a second XOR operation on the first data and the first result data to generate the second data, storing the generated second data in the data buffer block, and writing the second data stored in the data buffer block in the first memory region.

Abstract: A storage system includes a host and a storage device. The host includes a host processor and a host memory buffer, wherein the host processor includes a CPU core controlling operation of the host and a cache dedicated for use by the CPU core. The host memory buffer includes a submission queue and a completion queue. The storage device is connected to the host through a link and communicates with the host using a transaction layer packet (TLP). The storage device includes a nonvolatile memory device (NVM) and a storage controller, wherein the host writes a nonvolatile memory express (NVMe) command indicating a destination to the submission queue, and the storage controller reads data from the NVM, directly accesses the cache in response to destination information associated with the destination, and stores the read data in the cache.

Abstract: A memory device includes; a first memory of first type, a second memory of second type different from the first type, and a memory controller. The memory controller receives an access request and workload information related to work of an external processor, processes the access request using the workload information, and accesses at least one of the first memory and the second memory in response to the access request.

Abstract: A memory controller for controlling a memory operation of a memory device includes: an error correction code (ECC) circuit configured to detect an error of first read data read from the memory device and correct the error; an error type detection logic configured to write first write data to the memory device, compare second read data with the first write data, detect an error bit of the second read data based on a result of the comparing, and output information about an error type identified by the error bit; and a data patterning logic configured to change a bit pattern of input data to reduce an error of the second read data based on the information about the error type.
