Abstract

See full text

A semiconductor memory device which includes multi-bit memory cells that store multi-bit data and memory cells that store data of fewer bits then that of the multi-bit data. Thus, the semiconductor memory device includes a plurality of memory cells which store n-bit (where n is a natural number that is equal to or larger than 2) data for one cell. Among the plurality of memory cells, h-bit (h≦n) data is stored in a memory MLC of a first region MLB, and i-bit (i
