Abstract

A dynamic read-write random access memory (DRAM) including a memory cell, a word line and a bit line. The memory cell has a capacitor and a MOS transistor which has a gate connected to the word line, a drain terminal connected to the capacitor and a source terminal connected to the bit line. The DRAM further includes a supply circuit for applying to the bit line a voltage level having a value between the voltage level of the word line and the voltage level of the drain terminal of the MOS transistor when the memory cell is not selected, so as to prevent leakage current from flowing through the MOS transistor.
