Abstract

PURPOSE: To reduce the cell area to make a high integration possible by correcting errors, which are generated in memory cell blocks or reproducing circuits, on the chip at a reproducing time.
CONSTITUTION: Parity generated in parity generation circuit 31 is stored in dummy memory cell blocks 5 and 6 according to information of memory cell blocks 1W4. Then, logical operation 32 is performed between respective information of blocks 1W4 and blocks 5W6 for every reproducing, and generated errors are corrected on the chip by helium atomic nucleus α rays.
