Abstract
A semiconductor memory device is provided. Especially, there is disclosed a technique capable of increasing a net die by employing a cell capacitor as a reservoir capacitor according to a set mode. The semiconductor memory device of the present invention uses the cell capacitor as the reservoir capacitor in a normal mode, and prevents each voltage from being applied to the cell capacitor in a burn-in test mode. The voltage applied to the cell capacitor or MOS transistor can be adjusted according to the set mode.
