Memory extension apparatus and the method of data transfer applied therein
First Claim
1. A memory extension apparatus, comprising:
- a file system;
a first interface, for providing external electrical connections to a first electronic device;
a protocol converter, for receiving a first command from the first electronic device via the first interface for converting the first command;
a processor, for receiving the converted first command of the first electronic device from the protocol converter;
a memory unit, wherein the processor utilizes the file system to access the memory unit for files corresponding to the converted first command; and
a trigger unit, for triggering the processor to generate a second command, for accessing the first electronic device through a pre-defined protocol when the trigger unit is triggered, wherein the protocol converter converts the second command and outputs the converted request command to the first electronic device via the first interface.

Abstract
A memory extension apparatus and the method of data transfer applied therein. The memory extension apparatus comprises a first interface, a protocol converter, a processor, a file system, a memory unit, and a trigger unit. The protocol converter receives a first command from the first electronic device via the first interface for converting the same. The processor receives the converted first command from the protocol converter, and utilizes the file system to access the memory unit for files corresponding to the converted first command. The trigger unit is for triggering the processor to generate a second command, for accessing the first electronic device through a pre-defined protocol when the trigger unit is triggered. Without sacrificing size and weight of the first electronic device, the invention provides memory extension, file backup, and file sharing without the need of an external host device.

13. A method of data transfer between a memory extension apparatus and a first electronic device, the memory extension apparatus comprising a first interface, a protocol converter, a processor, a file system, a memory unit, and a trigger unit, the method comprising:
-
generating a request command by the processor when the trigger unit is triggered and the processor is triggered by the trigger unit;
if the request command is for upload function, sending a upload command by the processor to the first electronic device through the protocol converter and the first interface, and accessing the memory unit by the processor according to the file system to obtain a first upload file for sending the obtained first upload file to the first electronic device through the first interface;
if the request command is for download function, sending a download command by the processor to the first electronic device through the protocol converter and the first interface, and receiving a first download file from the first electronic device via the first interface; and
storing the first download file by the processor in the memory unit according to the file system. - View Dependent Claims (14)
