摘要： A redundant circuit that includes a combination of fuses and anti-fuses, and which may be used during various phases of the manufacturing process (e.g., during wafer test or final test) to replace a defective circuit. The redundant circuit includes (1) a replacement circuit (e.g., a redundant memory cell) that is configurable to replace a defective circuit, and (2) supporting circuitry for the replacement circuit. The support circuit is configurable to provide a control signal (e.g., to activate a word line) for the replacement circuit and further includes at least one fuse and at least one anti-fuse. The fuses or anti-fuses may be programmed to provide a programmed value (e.g., a programmed address) for the replacement circuit. The redundant circuit can be efficiently fabricated within a memory device, and may also be used for other circuits and applications.

摘要： The system described herein provides a minimized skew generator that has very small timing variation. Four phase signals are compressed into one signal including the four phase information. Therefore, the signal with all of the phase information travels on the same line, thus avoiding the concerns of skewing based on different sizes of metal lines. Since there are two rising edges and two falling edges within one signal, an enable line is utilized to select between the first and second, rising and falling edges. With this processing, the system has only one critical signal output, thus requiring only one signal line. Skewing of the signals and the amount of power required are both reduced.

摘要： The present invention relates to an apparatus and method for estimating a frequency offset in a wireless telecommunication system. The present invention does not estimate an initial frequency offset using a preamble which is the initial symbol of a frame upon estimation of the frequency offset in the wireless telecommunication system, but estimates a frequency offset using correlation of a cyclic prefix (CP) existing in each symbol, thereby eliminating a need to reproduce information about separate preamble signals and preamble signals, and easily estimating a frequency offset using only input signals.
