US Patent 11593023 Memory controller and method of operating the same

A memory controller and a method of operating the same may move data from a first memory buffer to a second memory buffer. The memory controller may include a host controller configured to receive host data corresponding to a program request from a host and to control transmission of the host data so that the host data is programmed to a memory device, a flash controller configured to receive flash data corresponding to a read request from the memory device and control transmission of the flash data to the host, and a memory buffer component including the first memory buffer and the second memory buffer configured to store the host data, flash data, or both. The memory controller is configured to control the memory buffer component so that the host data, flash data, or both are moved from the first memory buffer to the second memory buffer.
