(English Abstract)
BIST(Built-in self test) is to detect various faults of the existing memory and BIRA(Built-in redundancy analysis) is to repair detected faults by allotting spare. Also, BISR(Built-in self repair) which integrates BIST with BIRA, can enhance the whole memory¡¯s yield. However, the previous methods were suggested for RAM and are difficult to diagnose disturbance that is NAND-type flash memory¡¯s intrinsic fault when used for the NAND-type flash memory with different characteristics from RAM¡¯s memory structure. Therefore, this paper suggests a BISD(Built-in self diagnosis) to detect disturbance occurring in the NAND-type flash memory and to diagnose the location of fault, and BISR to repair faulty blocks.
