Abstract: A storage device includes a non-volatile memory, and a storage controller configured to read a non-encrypted command from a memory outside the storage device. The storage controller is also configured to transmit encrypted data to the non-volatile memory or the memory based on the non-encrypted command, and transmit a non-encrypted completion to the memory. The non-encrypted completion indicates a result of executing the non-encrypted command.

Abstract: The present disclosure provides methods and apparatuses for processing data. In some embodiments, the method includes operating a device by transmitting, to a host, first data using a plurality of direct memory access (DMA) channels regardless of an order of each DMA channel of the plurality of DMA channels. The method further includes obtaining an optimal number of the DMA channels based on a process capacity of a receiver buffer of the host. The method further includes transmitting, by the device to the host, second data based on the optimal number of the DMA channels.
