Abstract
A semiconductor device for detecting and compensating for a propagation delay of a tri-state bidirectional bus connected between a master block and a plurality of slave blocks. The master block controls the slave blocks. A bidirectional bus connects the master block and each of the slave blocks and accommodates transmission of data therebetween. A unidirectional bus is connected between the master block and each of the slave blocks. The unidirectional bus accommodates the transmission of control signals generated in the master block to the slave blocks wherein the master block detects a propagation delay time between the master block and the slave blocks. The master block counts the number of clocks from a time when a selected slave block transmits an allocated symbol to a time when the allocated symbol reaches the master block such that a propagation delay time between the master block and the selected slave block is detected and stored.
