Abstract
A storage controller includes a CPU for controlling each component in the storage controller; a ROM for storing programs executed by the CPU and data required for this execution; a RAM employed as a work area when the CPU executes the programs; a first ASIC (USB system) for controlling data transfers based on the USB standard; slots in which can be inserted various external memory units; a second ASIC (external memory system) for controlling data accesses to the external memory units to read data therefrom or write data thereto; and an address bus and a data bus connecting these components to one another.
