SEMICONDUCTOR INTEGRATED CIRCUIT

摘要

PURPOSE: A semiconductor integrated circuit is provided to greatly reduce number of chip through via by interfacing the signals activated in different operational range through one common chip through via. CONSTITUTION: A master chip(210) includes a multiplexer(212). The multiplexer multiplexes internal output signals(SIGNAL_M1,SIGNAL_M2) to output signals(SIGNAL_TSV1, SIGNAL_TSV2) and outputs the output signal. A slave chip(220) includes a demultiplexer(222) for outputting internal input signals(SIGNAL_S1,SIGNAL_S2). A common chip through via(230) is formed to interface the output signal of a master chip to a slave chip. A bump pad is formed to be electrically connected between the common chip through via and the slave chip.
