The storage element of the DRAM memory cell is the capacitor labeled (4) in the diagram above. The charge stored in the capacitor degrades over time, so its value must be refreshed (read and rewritten) periodically. The nMOS transistor (3) acts as a gate to allow reading or writing when open or storing when closed. WebDec 29, 1998 · A bit line 108a on the outermost side (uppermost row in FIG. 8) is not connected to the sense amplifier circuit 130 but is used as a dummy bit line. The outermost word and bit lines are therefore used as dummy lines. MISFETs corresponding to the dummy word and bit lines do not operate as memory cells.
