Abstract
A method for making a sense amplifier capable of achieving high-speed sensing operation as well as incurring less influence from electrostatic capacitance of bit lines in a high-integration semiconductor memory (DRAM) device is disclosed. The DRAM device includes a plurality of word line pairs and bit line pairs, and a plurality of memory cell arrays with a plurality of memory cells, and further includes discrete sense amplifier circuits connected to each of the memory cell arrays, common sense amplifier circuits coupled between the discrete sense amplifiers, and separation circuits controlled by a given control signal and connected between the discrete sense amplifier circuits and common sense amplifier circuits.
