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.
