Abstract
Each of twin-cell units each formed of two DRAM cells has a cell plate electrically isolated from the cell plates in the other twin-cell units. Thereby, voltages on two storage nodes storing mutually complementary data in the same twin-cell unit change similarly to each other owing to capacitive coupling.
