    摘要: A memory device includes a plurality of test mode signal generating units and a plurality of test circuits. Each test mode signal generating unit generates a respective test mode signal for a respective test circuit. The test mode signal generating units generate the test mode signals in series for the test circuits. Each test mode signal generating unit may be disposed within a respective test circuit such that wiring is not necessary from the source of the test mode signals to the test circuits.

    摘要: A circuit for testing a semiconductor memory device includes a data comparator and a signal aligner. The data comparator compares a first output data and a second output data provided from an output buffer circuit. The data comparator determines whether logical states of the first output data and the second output data are identical to generate a comparison signal. The signal aligner aligns the first output data and the comparison signal, and generates a plurality of test signals in response to a clock signal. The test signals includes an even bit test data, an odd bit test data, an even bit comparison test data and an odd bit comparison test data. The even bit data and the odd bit data are simultaneously tested by using one pattern, and a correct test result is yielded even when test data are all inverted.

    摘要: A majority voter circuit is configured to generate a selecting signal based on first input data and inverted first input data. The first input data and the inverted first input data each include an odd-number of bits, and the odd-number of bits include bits of a first type and bits of a second type. The generated selecting signal is indicative of which of the first type and the second type of bits in the first input data are in the majority.
