Abstract: A bridge device includes a first controller and a second controller. The first controller includes a first transmission interface. The second controller includes a second transmission interface. The first transmission interface and the second transmission interface are flash memory interfaces. In a program mode, the first transmission interface receives a first command from the second transmission interface and obtains first transfer data from a bus in response to the first command. A value of the first command is optionally set to a first value or a second value. The first value indicates a memory command transfer operation in a first direction and the second value indicates a memory data transfer operation in the first direction. The first transmission interface processes the first transfer data according to the value of the first command to obtain a memory command or written data.

Abstract: A bridge device for bridging a host device and a data storage device includes a first controller and a second controller. The first controller includes a first transmission interface. The second controller is coupled to the first controller and includes a second transmission interface. The second transmission interface is coupled to the first transmission interface through a bus. The first transmission interface operates in a slave mode and the second transmission interface operates in a master mode. The first transmission interface and the second transmission interface generate multiple transfer data chunks in compliance with a common bridge transfer format to perform transfer operations in dual directions for respectively transferring a command and data between a host device and a data storage device.
