Abstract
A semiconductor memory device includes: a determination section; an expected value control section; and an accumulation section. The determination section determines coincidence/non-coincidence between input data and an expected value. The expected value control section catches a read expected value in a read operation only. The accumulation section catches a determination result according to an accumulation-transmission signal. When the accumulation-transmission signal is in a transmission state, a determination result is caught, while when the accumulation-transmission signal enters an accumulation state, the next determination result is caught in a case of coincidence determination and once a non-coincidence determination result is caught, thereafter the non-coincidence determination result continues to be held.
