摘要： This invention relates to a circuit technique for rapidly and efficiently correcting for read and write data errors in a digital semiconductor memory. More generally, this can also be in any type of digital memory or digital communication channel. As semiconductor memories get smaller and smaller, the memory cells are subject to higher rates of manufacturing defects and soft errors. Correction of manufacturing defects is achieved through extensive testing and use of redundant memory cells to replace defective memory cells. Soft errors are very difficult to detect and correct and only the simplest parity check codes have been implemented. The cost in terms of delay time and computational complexity are barriers to the implementation of ECC. This invention represents a device that introduces very little delay and requires minimal hardware complexity to implement.

摘要： A wide dynamic range sensor employing simple sensing circuitry formed on a single chip provides accurate measurements of an incoming signal capable of varying of a wide dynamic range. Responsive to an incoming signal, the sensor generates output pulses having a frequency which is representative of a property of the incoming signal. By measuring the output pulse frequency, an accurate indication of a property of the incoming signal capable of varying over a range of 10.sup.5 or more is possible over the entire signal range. A plurality of sensors can be colocated on a single chip for providing a wide dynamic range sensor array.

摘要： The performance of sigma delta analog to digital conversion systems is enhanced by instrumenting the modulator with an observation circuit which provides quantized estimates of the modulator's state values. These state estimates are filtered separately and the result is added to the output of the decimator. This technique lowers the noise floor of the signal band and achieves performances better than those predicted by the spectrum of the modulator output. Error Correcting is particularly well suited to very low oversampling ratios. Finally, the correction is calculated and added in the digital domain so that this technique can be employed with existing architectures with only minor modifications.

摘要： The anti-fuse circuit includes three sub-blocks: a multiplexer having inputs of control signals and addresses and yielding the activation of a programming signal and program addresses; a programming voltage generator consisting of an oscillator and a charge pump; and an anti-fuse unit circuits for the program/read of anti-fuse states. For an anti-fuse program at the special test mode, a program address generation circuit having inputs of control signals and addresses activates the programming voltage generator and makes a special or program address for selection of anti-fuse. In the normal mode, the program address generation circuit and an internal power generator remain at an inactive state. In anti-fuse unit circuit, the program address and the programming voltage signal from the programming voltage generator serve to switch the terminal of the anti-fuse up to a programming voltage level when the anti-fuse is selected for programming of anti-fuse elements.
