摘要: The invention relates to a method for resetting at least one circuit part of an integrated circuit, in particular a synchronous semiconductor memory, in which a clock signal and a clock signal that is inverted with respect to the latter are provided in order to clock the integrated circuit, and in which, when a reset condition is present, an item of reset information is coded onto the clock signal or onto the inverted clock signal. The invention also relates to a circuit arrangement for carrying out the method according to the invention, having a clock suppression device and a decoder circuit, which is intended to extract the reset information from the clock signal or from the inverted clock signal.

摘要: Latency time circuit for an S-DRAM (1), which is clocked by a high-frequency clock signal (CLK), for producing a delayed data enable signal for synchronous data transfer through a data path (38) of the S-DRAM (1), having a controllable latency time generator (57) for delaying a decoded external data enable signal (PAR) with an adjustable latency time, which a comparison circuit (60) which compares a cycle time (tcycle) of the high-frequency clock signal (CLK) with a predetermined signal delay time of the data path (38), and reduces the latency time of the latency time generator (57) by the cycle time if the signal delay time of the data path (38) is greater than the cycle time (tcycle) of the clock signal (CLK)

摘要: An apparatus for generating a second signal having a clock based on a second clock from a first signal with a first clock comprises first and second means for sampling the first signal to determine whether the first signal has a predetermined logic state, wherein first means samples the first signal with the second clock, and second means samples the first signal with a clock phase shifted to the second clock. Means for generating the second signal generates the second signal based on the second clock if it has been determined by at least one means for sampling that the first signal has the predetermined state. Especially for time critical applications, such as a DDR-RAM, a valuable latency saving is provided by the present invention.

摘要: A Method for initializing an asynchronous latch chain is described, wherein data are taken over through a latch stage at the beginning of the latch chain upon a request signal, the method comprising starting of a clock creation means, like for example a DLL (DLL=delay locket loop), for creating an internal clock on the basis of an external clock, resetting the asynchronous latch chain and applying a start signal to a request signal generation circuit whereupon the creation of a first request signal is enabled on the basis of the internal clock after the clock creation means is settled and after the asynchronous latch chain is reset.

摘要: In a method for reducing interferences in a voice signal, a noise reduction method is applied to the voice signal, and spectral psychoacoustic masking is taken into account. A spectral masking curve is determined both for the input signal and the output signal of the noise reduction method. By comparing the signal portions exceeding the respective masking curve, newly-audible portions are detected in the form of interference in the output signal and subsequently damped selectively.
