Abstract
The conventional I/O devices of a storage element, such as memory card, have a built-in microprocessor control unit (MCU) for executing the I/O commands. The demand of MCU increases the cost. Besides, the capacity of the storage element supported by the device is depend on the firmware inside the MCU. Since the updating of firmware is a tough job, the supportability is lack of elasticity. This invention discloses a method for driving the I/O device of storage element that strengthens the device driver to get rid of the MCU. The capacity supported hence can be raised by merely updating the device driver.
