Abstract: 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.

Abstract: The invention is related to a control method to make IC's operation mode to be provided with uncertainty, wherein a Genetic Random Number is produced with the first use of IC, and a Run-Time Random Number is produced with every use of IC, both numbers are produced from the Random Number pool in IC, and then produce a long serial number through hash function, which include a plurality of control bits to serve as the function control of data shuffle for IC data access, path and direction for data flow, etc. The said long serial number varies with the random number during each time of execution, thus the control method of the long serial number is various and the IC's operation mode is provided with uncertainty. As IC is applied to e-commerce, data security or encryption/decryption process, due to the uncertainty of IC's behavior, a hacker cannot catch the fixed IC's operation mode to break through it just through analysis to a single IC, therefore the data security can be protected.

Abstract: A method and system for emulating a secret code between a first hardware module to a second hardware module. First, the secret code that is initially stored in the first hardware module is transformed into a transformed secret code according to a transformation pattern randomly selected from a set of possible transformation patterns. Then the transformed secret code is transferred to the second hardware module. Next, the second hardware module can repeatedly guess a hypothetical secret code from the transformed secret code by using a transformation pattern selected from the possible transformation patterns and reversing the effect of the selected transformation pattern on the transformed secret code. In addition, the hypothetical secret code is used to encode a test sample, and the encoded test sample is sent back to the first hardware module. Accordingly, the first hardware module can verify the validity of the current hypothetical secret code by checking the encoded test sample.

Abstract: 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.

The data buffer comprises a plurality of flip flops, a multiplexer, a test platform, a repair unit, and a buffer rearrange manager.

Furthermore, the area of the data buffer and number of gates are reduced greatly.

Abstract: A framework and a respective method for inter-element channel transmission are introduced mainly by constructing a plurality of connecting channels between elements. Each channel further includes a plurality of signal lines. Implicit meaning (data, address or control signal) in the signal line is realized by judging the variation of duty cycle in a clock signal, or an A/C line is used to define the transmission of a start signature, an end signature, address signals and control signals. By providing the transmission models of the present invention, each channel can operate independently, perform unidirectional transmission of address and data signals, and adjust the channel arrangement in accordance with practical requirements. Thereby, the signal transmission between elements can be highly mobile, the idle transmission time between elements can be greatly reduced, and the optimal transmission efficiency can be achieved.
