PROBLEM TO BE SOLVED: To provide a flash memory capable of transferring data of a plurality of pages within a short time in a memory that uses a multi-value technology.SOLUTION: The flash memory includes: a memory cell array including a plurality of memory cells each for storing data of n bits (n is an integer of 2 or more); a plurality of word lines connected to the gates of the memory cells; a plurality of bit lines connected to the memory cells; a sense amplifier for detecting data stored in the memory cells via the bit lines; a data latch of m×n bits for storing the data of n bits stored in each of m (m is an integer of 2 or more) pieces of memory cells connected to a certain word line; and a multilevel interface capable of simultaneously transferring data of 2 bits or more from the data latch to the outside. |
