Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
192 words
A semiconductor memory device comprising: at least one memory cell array means having N memory blocks; n buffer means for temporarily storing data to be transferred with respect to said memory means, respectively connected to said memory blocks and divided into n groups; n buffer selection means for selecting data transferred to and from said buffer means and each connected to a corresponding group of said buffer means; driver means; data selection means for selecting data transferred to and from said driver means; n data buses for transferring data between said n buffer selection means and said data selection means; and control means for supplying control signals to said buffer selection means and data selection means in each operation cycle, causing one of said buffer means belonging to a corresponding one of said groups of buffers to be selectively connected to a corresponding one of said data buses via a corresponding one of said buffer selection means, and causing said data buses to be sequentially connected to said driver means via said data selection means, thereby permitting serial data to be transferred with respect to said memory means via said data buses.
