PURPOSE:To perform quickly the test, evaluation and relief processes, by increasing the count value of a fail counter every time a defective storage cell is detected while a test is given to a sampled semiconductor storage device by a tester. CONSTITUTION:A tester 20 gives an increment to a fail counter 21 when it detects a defective cell under test of a sampled memory 1 and stores row and column ...

PURPOSE:To improve the processing efficiency without having countermeasures to each error but by ignoring such errors as much as possible, by reading out the key contents on a key storage and comparing them with the key information on a program status word. CONSTITUTION:When a main memory 1 receives accesses successively by an advance control, an access is also given to a key storage 2 at a time. ...
