Abstract:
A data storage device in a two-layer control structure is provided. A control unit of the data storage device has a command processor and a first non-volatile memory (NVM) controller. The command processor is operative to communicate with a host. The first non-volatile memory (NVM) controller operates a first NVM of the data storage device. Earlier than the command processor operates according to a ROM image corresponding to the command processor, the first NVM controller operates according to a ROM image corresponding to the first NVM controller to access the first NVM to get a firmware image for the command processor and loads the command processor with the firmware image.
