Data storage circuits are connected to the bit lines in a one-to-one correspondence. A write circuit writes the data on a first page into a plurality of first memory cells selected simultaneously by a word line. Thereafter, the write circuit writes the data on a second page into the plurality of first...http://www.google.fr/patents/US7443724?utm_source=gb-gplus-shareBrevet US7443724 - Semiconductor memory device for storing multivalued data
