Enhanced Backup/Operation Execution Portable Memory Devices

Background:


Flash memory is nonvolatile computer memory that can be electrically erased and reprogrammed. It is a technology that is primarily used in memory cards and USB flash drives for general storage and transfer of data between computers and other digital products. It is a specific type of EEPROM (Electrically Erasable Programmable Read-Only Memory) that is erased and programmed in large blocks; in early flash the entire chip had to be erased at once. Flash memory costs far less than byte-programmable EEPROM and therefore has become the dominant technology wherever a significant amount of nonvolatile, solid-state storage is needed. Example applications include PDAs (personal digital assistants), laptop computers, digital audio players, digital cameras and mobile phones. It has also gained popularity in the game console market, where it is often used instead of EEPROMs or battery-powered SRAM for game save data.

Problem


Presently, data transfer between flash devices are only possible by using a PC. For example, to transfer data between USB Hard Disk and xD-Picture Card*, a user needs to connect the devices to a PC and transfer these files manually. Such manual, labor intensive processes are often ignored which may lead to expensive data loss. The following proposed invention improves the current method by removing the need to have a PC and automate the data transfer process.
