Patent Number: 6,295,243

Title: Semiconductor device

Abstract: A semiconductor integrated circuit includes a plurality of semiconductormemory devices implemented as DRAMs and an output selector on the samechip. External terminals of the chip include: terminals for inputting aninverted row address strobe signal /RAS to the respective semiconductormemory 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 memorydevices are controlled by the output selector, passed through a commontest bus and then output from a common external terminal.
