A bridge 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 coupled to the first transmission interface. The first transmission interface and the second transmission interface are both flash memory interface.

Bridge device and data storage system

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.

Bridge device and method for transferring command and data between a host device and a data storage device

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.

Memory controller, bridge device and method for transferring command and data between memory controllers

A data storage device includes multiple storage modules. Each storage module includes a storage which having a memory device and a first memory controller and a second memory controller. The first memory controller is coupled to the memory device for accessing the memory device. The second memory controller is coupled to the storage for accessing the storage. The first memory controller includes a first transmission interface. The second memory controller includes a second transmission interface. The first memory controller and the second memory controller communicate with each other through the first transmission interface and the second transmission interface.
