Abstract: A data writing method for writing data from a host system into a flash memory chip is provided, and the flash memory chip have a plurality of physical blocks. The method includes receiving a host writing command and write data thereof, and executing the host writing command. The method also includes giving a data program command for writing the write data into one of the physical blocks to the flash memory chip, and giving a command for determining whether data stored in the physical block has any error bit. Accordingly, the method can effectively ensure the correctness of data to be written into the flash memory chip.

Abstract: A storage device, a memory controller, and a data protection method are provided. The method includes when receiving a read command sent by a host, adopting a corresponding output flow rate limit to determine an operation that is executed on read data corresponding to the read command by the host according to location information included in the read command or a type of a transmission interface between the host and the storage device. The method also includes executing an interference procedure by the storage device to prevent the read data from being copied to the host or slow down the speed of copying the read data to the host when identifying that the operation is a copy operation.

Abstract: A method and a system for protecting data, a storage device, and a storage device controller are provided. In the present method, when a host accesses data in the storage device, whether the host performs a play operation or a copy operation on the data is first determined. If the host performs the play operation on the data, the storage device continues to execute the play operation so as to allow the host to access the data. On the other hand, if the host performs the copy operation on the data, the storage device executes an interference procedure so as to prevent or retard the data from being copied into the host.

Abstract: A hot plug electronic device with high using safety is provided. The hot plug electronic device includes an operation circuit, a voltage regulator and an over-thermal protection device. The operation circuit is used for communicating with an external host. The voltage regulator is coupled to the operation circuit for supplying power to the operation circuit. The over-thermal protection device is coupled to the voltage regulator for sensing the present temperature of the hot plug electronic device, and accordingly controlling the voltage regulator to normally supply/stop supplying the power to the operation circuit.

Abstract: The invention presents a programming method for a non-volatile memory with a bit signal to be programmed unidirectionally. The method includes the steps of a) providing first data each having a first number of sequential bits of first status in a data page in a non-volatile memory, b) decoding the first number of sequential bits of the first status in the first data into a second number of sequential bits of second status, and c) programming second data in a portion of the data page where the first status has been decoded to the second status.

Abstract: An expandable integrated circuit (IC) and an operation procedure thereof are provided. The expandable IC comprises the CPU and a RAM for writing data or program for correction into the CPU so that the manufacturer need not replace the ROM when the data or program in IC needs to be corrected or modified. Therefore, not only the replacement cost of ROM can be avoided but also the recordable or executable program can be effectively expanded and thereby providing great convenience to the manufacturer.

Abstract: A wireless sound apparatus capable of picking up the MP3 formatted file transmitted by a wireless information product and then the MP3 formatted file is encoded/decoded by the MP3 encoder/decoder/recorder IC unit into an analog signal that can be output by the speaker or MP3 formatted data can be recorded for storing into the wireless sound apparatus. Thus there is no need for the user to carry MP3 player or portable ROM/PDA for listening to music. Thus, by using the wireless sound apparatus of the present invention, the user is able to enjoy the music without any limitation.
