CIRCUIT AND METHOD FOR GENERATING ON DIE TERMINATION SIGNAL, SEMICONDUCTOR APPARATUS USING THE SAME

摘要

PURPOSE: A circuit and a method for generating an on die termination signal, a semiconductor apparatus using the same are provided to control the length of preamble of a data strobe signal by changing a generation time of the on die termination control signal. CONSTITUTION: A latency unit(110) receives a clock and an on-die termination signal and generates a first delay on-die termination signal and a second delay on-die termination signal. An on die termination control signal generating part(100) provides one of the first and second delay on die termination signal as the on die termination control signal. .
