    • A DRAM array has a row decoder means 2 and a column decoder 3 which are connected to a word line and a bit line of a cell matrix portion, respectively. The column decoder means 3 comprises a plurality of bit switches 44 and 46 for connecting a predetermined bit line to an output bus. Local latches 36 store data bits, each of the local latches provide for one group of bit lines 32 which is a unit of predetermined number of bit lines. The bit switches are arranged in a hierarchical structure, and connection between the bit line and the output bus is attained by two bit switches connected in series thereby load capacitance on the data lines 52 and 56 being able to be reduced. Data in respective local latches 36 is stored in the local buffer 74 in a predetermined order so that it can be burst transferred at a high speed.
    • DRAM阵列具有分别连接到单元矩阵部分的字线和位线的行解码器装置2和列解码器3。 列解码器装置3包括用于将预定位线连接到输出总线的多个位开关44和46。 本地锁存器36存储数据位,每个本地锁存器提供一组位线32,位线32是预定数量的位线的单位。 位开关以分层结构布置,并且通过串联连接的两位开关来实现位线和输出总线之间的连接,从而可以减少数据线52和56上的电容。 各个本地锁存器36中的数据以预定顺序存储在本地缓冲器74中,使得其可以以高速突发传送。
