Abstract: A flash memory and a method for utilizing the same are disclosed. The method for utilizing a flash memory includes the steps of: a) providing a flash memory of a single chip; b) formatting the flash memory and marking bad blocks of the flash memory as a bad-block area free of reliably saved data; c) calculating a capacity of an available memory with the flash memory, wherein the available memory excludes the bad-block area of the flash memory; and d) dividing the available memory into a first storing memory and a second storing memory, wherein the first storing memory and the second storing memory have different capacities.

Abstract: A security system for a flash memory and a method thereof are disclosed. The method of security system for a flash memory, includes the steps of a) providing a predetermined limit signal for a host system; b) defining a specific signal stored in the flash memory installed with a identification program for indicating a capacity of the flash memory; c) comparing the specific signal with the predetermined limit signal while the flash memory is connected to the host system; d) inhibiting access to the identification program of the flash memory if the specific signal does not correspond to the predetermined limit signal, but a residual space of the flash memory is available.

The method for utilizing a flash memory includes the steps of: a) providing a flash memory of a single chip; b) formatting the flash memory and marking bad blocks of the flash memory as a bad-block area free of reliably saved data; c) calculating a capacity of an available memory within the flash memory, wherein the available memory excludes the bad-block area of the flash memory; and d) dividing the available memory into a first storing memory and a second memory, wherein the first storing memory and the second storing memory have different capacities.

Abstract: A portable storage device with identifying function is provided. The portable storage device comprises a data transmission interface, for electrically connecting to a host end; a memory transmission interface; a microcontroller, having a smart card engine and electrically connected to the data transmission interface and the memory transmission interface respectively; and a memory, having a personal identification number (PIN) stored therein and electrically connected to the memory transmission interface.

Abstract: The present invention discloses a multimedia player, which has a controller chip separately connected to an audio/video transmission interface, a hard disk, a USB connecting interface and a control interface, and the controller chip installs a digital signal processing (DSP) chip and a USB controller. Since a hard disk is used as a storage device for the multimedia player, the multimedia player can have more data storage spaces to lower the cost of video recording or audio recording, and thus further lowering the price of the product and stimulating consumer's desire for the purchase. The USB connecting interface is connected to an electronic product having a host, so that the multimedia player can directly play the data stored in the electronic product having a host or store data into the hard disk of the multimedia player.

Abstract: The present invention is related to a portable storage device for personalizing computer, wherein an application program is stored in the portable storage device. The portable storage device has a connector for connecting to the connecting port of an electronic device. When the connector and the connecting port are electrically connected, the application program is executed to output the personal profile of the portable storage device to the electronic device, or the personal profile of the electronic device is stored in the portable storage device. Thus, the user can readily change the personal profile in the operating system, so that the task may be accomplished accurately and efficiently, and the problems caused by the operational interface as described in the prior art may be avoided.

Abstract: A multimedia card reader is disclosed. The card reader has a USB connector; a slot, for receiving a memory card; a data storage device, for saving/retrieving/transmitting data into/from/to the memory card; and a digital signal processor; a USB controller, connected to the digital signal processor and the USB connector, the date storage device and the slot; a signal amplifier, connected to an audio signal output terminal, wherein the digital signal processor is connected to the signal amplifier and an video signal output terminal, wherein an audio or a video data is converted into an audio signal or a video signal by the digital signal processor, and wherein the audio signal is transmitted to the signal amplifier and output via audio signal output terminal or the video signal is output via video signal output terminal.
