Abstract:
An address generation circuit generates a target address to be tested in a memory. A test data generation circuit generates write data for the address and expected value data for read data from the address. A judgment circuit compares matching/non-matching of the read data and the expected value data, for each address, judges that error correction is possible when the number of non-matching bits is within a range of numbers of bits to be error-corrected by an ECC circuit, and judges that error correction is not possible when the number is not within the range.

Claim (Index 9):
The semiconductor device according to  claim 1 ,\n wherein the judgment circuit has\n a bit comparison circuit which compares matching/non-matching of the \u201cn\u201d bit read data and the \u201cn\u201d bit expected value data for each address, and outputs an \u201cn\u201d bit comparison result signal in which each bit is at a first logical level or a second logical level in accordance with the matching/non-matching of each corresponding bit, \n a fourth logical gate which judges whether at least one bit of the \u201cn\u201d bit comparison result signal is at the second logical level, and \n a 1-bit error decode circuit which judges whether only 1 bit in the \u201cn\u201d bit comparison result signal is at the second logical level, and outputs a predetermined logical level when only 1 bit is at the second logical level.
