Abstract
A semiconductor memory device having a high speed for a data transmission includes a plurality of cell blocks, each having a plurality of unit cells for storing data; a plurality of local bit line sense amplifying block, each for sensing and amplifying the data stored in the N number of cell blocks; a global bit line sense amplifying block for latching the data amplified by the local bit line sense amplifying blocks; and a data transferring block for transmitting the data from the local bit line sense amplifying block to the global bit line sense amplifying block.
