Abstract
A synchronous semiconductor memory device includes a plurality of main data lines each coupled between a block sense amplifier array and a data output buffer. Each main data line prefetches a plurality of cell data segments from memory cells corresponding to an input/output port and transmits the cell data to the data output buffer. The memory device also includes a pass/latch part connected to one or more corresponding block sense amplifiers within a corresponding block sense amplifier array. The pass/latch part receives a plurality of cell data segments in parallel from the block sense amplifiers and transmits them in series to a corresponding main data line. This invention reduces a chip size and peak electric current of the semiconductor device by minimizing the number of main data lines required for prefetch operations.
