Abstract: The present invention discloses a method for managing memory blocks in a flash memory. The method is first to calculate the total number of good blocks and total number of bad blocks in the flash memory, and then all the good blocks and the bad blocks will be evenly allocated to each segment according to the number of segments contained in the flash memory. After the allocation, the allocation information will be recorded in one good block to form a data block so that when the flash memory is executing initialization, the controller chip may find the data block, and store the data in the SRAM (static random access memory) of the flash memory. Then, according to the data stored in the SRAM, the controller chip may generate a corresponding table for the block contained in the segment according to the data stored in the SRAM. As a result, the flash memory may be used with lower capacity and may obviate the problem of being unusable when the flash memory contains the excessive amount of the bad blocks.

Abstract: A portable storage device is provided. The portable storage device comprises a memory having a hidden block, a first program block, a general block and a security block. A user's password is stored in the hidden block and a password-identifying program is stored in the first program block. When a host executes the password-identifying program, the user is asked to input a password that is compared with the user's password stored in the hidden block. If the password inputted by the user matches with the user's password stored in the hidden block, the user is allowed to access to data stored in the security block and to process data retrieval/storage therein.

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: The present invention provides a method for managing incoming calls of a mobile phone. The mobile phone includes a control circuit and a volume detector. The method includes (a) receiving a call signal by the mobile phone, (b) detecting environmental volume surrounding the mobile phone with the volume detector, and (c) executing a first managing process with the control circuit when the detected surrounding volume exceeds a predetermined value, or executing a second managing process with the control circuit when the detected surrounding volume does not exceed the predetermined value.

Abstract: A method of filtering messages received on a receiving telephone apparatus includes receiving a message from a calling telephone and applying filtering rules to the message. A first filtering rule includes filtering the message if a telephone number of the calling telephone contains less than a predetermined number of digits. If the message satisfies at least one of the filtering rules, a filtering process is then executed on the message.

Abstract: An application IC that can be applied in the control system of a memory storage device for the USB device for communicating with a server for receiving, reading and writing commands from the server and to access to the data stored in various memory storage devices is provided. Alternatively, the application IC can support the server, including IDE portable information product for data transmission. The data transmission having these two different specifications can share the same data source in certain mechanism. In this mechanism, the USB server is in the first priority transfer mode, the IDE server will take action only when the USB server is unavailable or discharged. When the IDE server is in operation mode, the interruption demand from the USB server is denied and after the IDE server completes the assignment, the interruption command from the USB server is executed.
