Abstract
A memory mat including EEPROM memory has a redundancy memory area for replacing a defective memory area occurring in a main memory area. The most feature of the invention is that a redundancy address memory area for storing address data of the defective memory area is provided in a part of an inforow memory area within the memory mat. The inforow memory area is constructed accessibly only at the time of a test mode.
