摘要： A dynamic random access memory device is subjected to a diagnosis upon completion of fabrication to see whether or not a defective memory cell is incorporated in memory cell sub-arrays, one of the input/output data buffer circuits incorporated therein transfers test bits in serial to a shift register which in turn transfers the test bits in parallel to data line pairs for writing the test bits into the memory cell sub-arrays, and a comparator compares the test bits read out from the memory cell sub-arrays with the test bit stored in the shift register for producing a diagnostic signal indicative of consistence or inconsistence between the test bits read out from the memory cell sub-arrays and the test bits in the shift register, thereby allowing an external diagnostic system with data pins less than the input/output data buffer circuits to carry out the diagnosis.
