Abstract: A storage device includes a memory controller, a buffer memory, and a memory device including a plurality of non-volatile memory devices connected to the memory controller via an identical channel. The memory controller is configured to generate a first command for performing a first DMA operation and a second command for performing a second DMA operation, adjust an output time interval between a first output time point of the first command with respect to a first non-volatile memory device among the plurality of non-volatile memory devices and a second output time point of the second command with respect to a second non-volatile memory device among the plurality of non-volatile memory devices, and is configured to add a time interval corresponding to the output time interval between an end time point of the first DMA operation corresponding to the first command and a start time point of the second DMA operation corresponding to the second command.

Abstract: An operation method of a storage device configured to communicate with an external device through an interface channel includes receiving an indicator of a first throttling level of a plurality of throttling levels from the external device, setting a first operation parameter based on a throttling predefined table (PDT) including a relationship between the plurality of throttling levels and a plurality of throttling performances, such that the interface channel has a first throttling performance from among the plurality of throttling performances, the first throttling performance corresponding to the first throttling level, receiving a first input/output (I/O) request from the external device through the interface channel having the first throttling performance caused by the setting of the first operation parameter, and processing a first operation corresponding to the first I/O request through the interface channel having the first throttling performance.
