Abstract
A semiconductor storage device includes a memory cell array including a plurality of word line groups and a plurality of blocks corresponding to the plurality of word line groups. Each of word line groups includes a plurality of word lines and each of the blocks includes a plurality of memory cells. The plurality of memory cells of each block are connected to the respective word lines of a corresponding one of the word line groups. The semiconductor storage device includes a row decoder including a plurality of word line group decoders corresponding to the plurality of word line groups, respectively. Each of the plurality of word line group decoders is configured to drive a word line independent from a word line driven in another of the word line groups, when all of the plurality of word line groups are activated in parallel.
