摘要： A structure and method for repairing SDRAM by generating a Slicing Table of Fault Distribution and using the size of SDRAM page as the partition basic block. The Slicing Table of Fault Distribution is generated at each booting or memory-testing, and the elemental range of the number of detected defects is formed. When the number of detected defects exceeds the elemental range, the limits of another partition block with a lower rate of defects are used to cure the defect. The repair bit is also encoded according to the Slicing Table of Fault Distribution, pointing to the remapping bit so that the access operation occurs at the remapping bit. As such, the cost of producing, testing and repairing SDRAM is greatly reduced.

摘要： A structure of controlled pipeline logic is disclosed. A random noise generator is added to the controlled pipeline logic. Moreover, each combinational logic element of the controlled pipeline logic is appended with an active bit. When no input flows into the controlled pipeline logic, the random noise generator will generate random noises, and the active bit will enforce the combinational logic element to accept the random noise as an input so that the controlled pipeline logic is always sustained in the active condition. The controlled pipeline logic is not exposing the internal functions thereof and avoiding improper monitoring and observation.

摘要： A data-processing system with an enhanced system controller supporting memory-remapping function. The system controller has an access control circuit, a page/remapping management circuit and an open/remapped address table. The open/remapped address table is used to store mapping tables for indicating the mapping relation of memory segments and addresses dedicated to peripheral devices. The page/remapping management circuit should maintain and use the mapping tables in various operating mode. In addition, the page/remapping management circuit can redirect access requests to proper memory segments according to the mapping table corresponding to the current operating mode. Therefore, peripheral devices can effectively access and process the data stored in various memory segments by the change of the operating modes, not by physical data transfer.

摘要： A lower inertial compact disk driving device is disclosed. The disk and laser head are static and optical unit device are used as a medium of the laser optical path. Furthermore, the focusing is realized. An optical unit device is used as a medium of the laser beam and a displacing device is used to change the position of the optical unit device. The focusing device has two rigid sliding tracks, one focus coil, and two permanent magnets. The rigid sliding tracks are used as a linkage. The focusing error from the laser beam passing through the optical unit device is converted into a focusing driving voltage which is applied to the focus coil so that a magnetic field is generated. This field is interacted with permanent magnets so that the focus coil moves up and down. Thereby, the rigid sliding tracks move up and down to drive the optical unit device to move.

摘要： This invention generally relates to a method and apparatus for securing data contents stored in a non-volatile memory. More specifically, data contents to be stored a flash memory are first partitioned into block based data and rotated such that the addresses are scrambled. During a read operation, a random sequence generated through a random number generator causes contents of the retrieved data to also include original and extra (dummy) data. Through filtering and reverse rotation, original data contents are recovered. Accordingly, data contents in the flash memory are protected against unauthorized access, revision, or modification.

摘要： A system and method for reducing data traffic between the processor and the system controller in a data processing system during the execution of a vector or matrix instruction. When the processor receives an operation command requiring that a large quantity of data be processed, the processor issues a local operation request containing the desired operation, addressing information of the operands and a destination location for the result to the system. The system controller includes a local operation unit for locally executing the local operation request issued from the processor. Because the operand data associated with the operation need not be transferred over the system bus connected between the processor and the system controller, the data traffic between the processor and the system controller is reduced.

摘要： A device and method for safely maintaining a secret code within an integrated circuit (IC) package. The complete secret code is divided into two parts. The first part of the secret code is stored in a non-volatile memory device, such as flash memories, and provided by an internal random number generator. The second part of the secret code is stored in a volatile memory device, such as registers, and provided by external visa data issued from an authority center. Such a configuration can guarantee that no one can ferret out the complete secret code by opening the sealed IC package. Accordingly, the secret code can be safely and confidentially maintained within the IC package.
