Abstract
A dynamic random access memory includes a memory cell array, sense amplifiers disposed at both sides of the memory cell array, and sub bit lines coupled to the sense amplifiers. The sub bit lines may be coupled to data busses through middle amplifiers. By use of such a memory architecture, a higher integration of a DRAM can be realized. Also, the handling of super large bit data, i.e. more than 1024 bits becomes possible.
