Hojun Shim

A data transferring method of a storage device is provided. The method may include transferring a first data to a first outbound area, transferring the first data sent to the first outbound area to a first area of a main memory corresponding to a first address programmed by an address translation unit, transferring a second data to a second outbound area in response to an indication that the address translation unit is to be reprogrammed, and transferring the second data sent to the second outbound area to the first outbound area.

Storage device and data transferring method thereof

A memory controller is provided. The memory controller may comprise a first interface configured to provide an interface for communications with a host, and a second interface configured to communicate with the host through the first interface and to provide an interface for communications with a memory. The second interface may include an emulation engine configured to generate a Direct Memory Access (DMA) setup Frame Information Structure (FIS) including ready state information for data communications with the host in response to a command transferred from the host. The second interface may include a storage engine configured to access the host to fetch a physical region descriptor (PRD) before the DMA setup FIS is received from the emulation engine.

Memory controller and operating method thereof

A data transfer method of a storage device which includes a host bus adaptor to communicate with an external host via a first interface and to communicate internally via a second interface is provided. The data transfer method may include issuing a write command and a read command to the host bus adaptor; performing a read direct memory access operation using the first interface in response to the write command and simultaneously performing a write direct memory access operation using the second interface in response to the read command; and generating frame information structure (FIS) sequences according to the second interface in response to the issued write command and the issued read command. The first interface may perform a full duplex data transfer and the second interface may perform a half-duplex data transfer.
