Abstract
A semiconductor device has a memory section including a first and second memory cell storing a data bit and error correcting bit, respectively. An error correcting section outputs a data signal containing an error-corrected data bit, using the error correcting bit and an information signal when the error is corrected. A test section outputs a first determination signal when the memory section is determined to be faulty by checking the data signal based on a program. A counter section counts the number of times by which the information signal is supplied thereto and outputs a second determination signal when the result of counting becomes equal to a reference value. A determining section determines that the memory section is faulty when one of the first and second determination signals is supplied thereto.
