摘要： A detector circuit and method for detecting a silicon well voltage or current to indicate an alpha particle or cosmic ray strike of the silicon well. One significant application for the detection circuit of the present invention is for the redundancy repair latches that are used in SRAMs. The redundancy repair latches are normally written once at power-up to record failed latch data and are not normally written again. If one of the latches changes states due to an SER (Soft Error Rate-such as a strike by an alpha particle or cosmic ray) event, the repair data in the redundancy latches of the SRAM would now be incorrectly mapped. The detector circuit and method monitors the latches for the occurrence of an SER event, and responsive thereto issues a reload of the repair data to the redundancy repair latches. A first embodiment of the detector circuit differentially detects the floating voltages of first and second silicon wells during periods of non-operation of the circuits fabricated in the first and second silicon wells. In a second embodiment, a detector circuit monitors the background voltage level of a single silicon well over first and second consecutive periods of time. A second application for the detection circuit is for traditional logic circuits.
摘要翻译：一种用于检测硅阱电压或电流以指示硅阱的α粒子或宇宙射线冲击的检测器电路和方法。本发明的检测电路的一个重要应用是用于SRAM中的冗余修复锁存器。冗余修复锁存器在上电时通常写入一次，以记录失败的锁存数据，并且通常不会再次写入。如果其中一个锁存器由于SER（软错误率（例如α粒子或宇宙射线的击穿））事件而改变状态，则SRAM的冗余锁存器中的修复数据现在将被错误地映射。检测器电路和方法监视锁存器以发生SER事件，并且响应于此，将修复数据重新加载到冗余修复锁存器。检测器电路的第一实施例在第一和第二硅阱中制造的电路的非操作期间差分地检测第一和第二硅阱的浮置电压。在第二实施例中，检测器电路在第一和第二连续时间段内监测单个硅阱的背景电压电平。检测电路的第二个应用是传统的逻辑电路。

摘要： Circuits and methods for measuring and characterizing random variations in device characteristics of semiconductor integrated circuit devices, which enable circuit designers to accurately measure and characterize random variations in device characteristics (such as transistor threshold voltage) between neighboring devices resulting from random sources such as dopant fluctuations and line edge roughness, for purposes of integrated circuit design and analysis. In one aspect, a method for characterizing random variations in device mismatch (e.g., threshold voltage mismatch) between a pair of device (e.g., transistors) is performed by obtaining subthreshold DC voltage characteristic data for the device pair, and then determining a distribution in voltage threshold mismatch for the device pair directly from the corresponding subthreshold DC voltage characteristic data. The voltage threshold mismatch distributions of different device pairs of a given circuit design can then be used to determine voltage threshold variations of the constituent circuit devices. The voltage threshold variation of the devices can be used to characterize the random variations of the given circuit.

摘要： An integrated circuit, such as a memory macro, includes multiple power rails supporting first and second voltage differentials, with the second voltage differential being smaller than the first voltage differential. Signal lines in the integrated circuit are driven with the small voltage swing, which is generated by small swing circuits. The integrated circuit further includes regeneration circuits, which are receiving small voltage swing inputs and are outputting first, or full voltage swings. The application of the small voltage swing to the signal lines saves power in the integrated circuit. A wide bandwidth, full-wordline I/O, memory integrated circuit has simultaneously operable connection paths between essentially all the memory cells that are attached to the same wordline and the corresponding I/O terminals, and it has a single ended data-line structure.
