Abstract
The semiconductor component is provided for connection to a test system. An external clock signal with a modulated duty ratio can be input to the semiconductor component at a connection provided for that purpose on the semiconductor component. The latter has a clock recovery circuit, which obtains a periodic clock signal from the modulated clock signal, and a shift register, to which the modulated clock signal can be fed in a manner clocked by the periodic clock signal and which provides a data signal. The present invention makes it possible, in particular in mass memory chips, to feed in clock signals and also program, address or data signals for the realization of BIST via just one connection contact.
