Abstract

A semiconductor memory apparatus includes a memory cell array having a multiplicity of data lines and a multiplicity of local amplifiers, each of the local amplifiers being associated with a data line. An amplifier group includes at least two amplifiers selected from the multiplicity of local amplifiers. Each amplifier has at least a pair of selection transistors for selecting a particular amplifier from the amplifier group. The selection transistors have a common gate, an unshared intrinsic diffusion region, and a shared intrinsic diffusion region, the shared intrinsic diffusion region being shared with an adjacent selection transistor from an adjacent amplifier.
