Abstract
The semiconductor memory configuration has at least two memory cell arrays. The open area between the strips of the sense-amp transistors in the two memory cell arrays contains dummy transistors. This avoids proximity effects at the edges of the sense-amp transistors adjoining the open area. The sense-amp transistors and the dummy transistors are arranged in a common, continuous diffusion region.
Claims3
A semiconductor memory configuration, comprising:
- at least two memory cell arrays provided with strips made up of components including sense-amps transistors and drivers;
- an open area being disposed between said at least two memory cell arrays;
- dummy components formed in said open area, said dummy componets being similar to adjacent said components of said memory cell arrays;
- and
- a common, continuous diffusion region in which said dummy componets and said adjacent components are arranged.
