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.
