| 1. A semiconductor memory device comprising:
a plurality of memory elements to which data is written by a write operation; and
a control circuit, wherein:
in a first write sequence, the control circuit simultaneously stores data in “n” (“n” being a natural number) numbers of said
plurality of the memory elements in the write operation and then the control circuit repeats the write operation and a verify
operation if any of said “n” numbers of the memory elements are memory elements written insufficiently in the verify operation;
and
in a second write sequence, the control circuit simultaneously stores data in “n” (“n” being a natural number) numbers of
said plurality of the memory elements in the write operation and then the control circuit repeats the write operation and
a verify operation if “k” (“k” being a natural number which is equal to or less than “n”) or greater numbers of said “n” numbers
of the memory elements are memory elements written insufficiently in the verify operation.
