Provided are a memory system and an operating method of the memory system. The memory system includes a memory controller configured to generate a first command and a second command in response to receiving a sequential command from a host, and a first memory device and a second memory device each configured to receive the first command and the second command, wherein the sequential command is a command to determine or indicates whether to access each of the first memory device and the second memory device, and the memory controller is further configured to determine whether to access at least one memory device among the first and second memory devices, transmit the first command to the first memory device when the first memory device is to be accessed, and transmit the second command to the second memory device when the second memory device is not to be accessed.

Memory system and memory controller that transmits commands to memory devices and operating method thereof

An operating method of a storage device is provided. The operating method includes: receiving a host read command from a host device; identifying whether a read path corresponding to the host read command corresponds to a first direct memory access (DMA) read path; and directly outputting, by a host DMA manager, read data stored in an output buffer of an error correction circuit to the host device based on the read path corresponding to the first DMA read path.
