Abstract
A data latch circuit group latches data read by a sense latch circuit group when a read voltage is supplied to a word line. These data are transferred to a read data conversion circuit and converted to 2-bit data. Thus, no operation processing may be performed through a bit line or a transistor in a memory cell array, whereby a read time can be reduced for reducing power consumption.
