Abstract

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.
