A storage unit made of flash array and a USB controller, is implemented to be compatible with then USB specification. The unit includes memory modules which can accept write commands and read commands and are erasable and non-volatile herein referred to as flash modules. The USB/flash controller is configured to provide USB functionality and compatibility alone with common flash operations such as programming reading and erasing the above mentioned components.A USB flash memory device includes at least one flash memory module, a USB connector, a USB controller, and an identification structure for holding memory size and manufacturing type information of the flash memory module. The USB controller is configured to send and receive USB-defined data packets to or from a host via the USB connector, to extract operation codes and logical addresses from the USB-defined data packets, and to carry out at least one of reads, writes and erases in the flash memory module in accordance with the USB-defined data packets, and to interpret the operation codes into corresponding commands. The USB controller is configured to activate a respective memory technology driver in accordance with the memory size and manufacturing type information in the identification structure. The activated memory technology driver is configured to perform the commands on the flash memory module corresponding to the logical addresses.
