Abstract: Example embodiments are directed to an apparatus and method for measuring a pulse width. A side-band signal generator may be configured to receive a given data pattern and output a side-band signal by modulating a pulse width of the received data pattern in a test mode. A phase detector may be configured to receive the side-band signal and a reference clock signal, and output a pulse signal corresponding to a phase difference between the received side-band signal and the reference clock signal. A charge pump may be configured to receive the pulse signal and output an output voltage by increasing or decreasing the output voltage based on the pulse signal. A pulse width measurer may be configured to receive the output voltage of the charge pump and determine whether pulses forming the side-band signal have appropriate widths based on whether the output voltage is included in a desired reference voltage range.

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.
