Abstract
A semiconductor integrated circuit includes a plurality of semiconductor memory devices implemented as DRAMs and an output selector on the same chip. External terminals of the chip include: terminals for inputting an inverted row address strobe signal /RAS to the respective semiconductor memory devices individually; and common terminals for inputting PRAUT, SLF, /CAS, ADR, /WE, /OE, CLK and TMODE signals to all the memory devices. The output signals TDQ, SRAS, MOUT and BITST of the semiconductor memory devices are controlled by the output selector, passed through a common test bus and then output from a common external terminal.
