Abstract
A semiconductor memory has a sense amplifier array shared by first and second memory cell arrays, which are selected by first and second selection signals. Interconnections between the sense amplifier array and the first memory cell array are controlled by a first transfer gate signal. When the first selection signal is inactive, the second selection signal is coupled through a first transfer gate driver to become the first transfer gate signal. When the first selection signal is active, the first transfer gate signal is decoupled from the second selection signal and driven to an elevated level.
