Abstract
A DRAM made in monolithic form, the cells of which each include a MOS transistor and a capacitor, a second electrode of which is common to all cells of a same row and is covered with an insulator, the insulator being coated with independent conductive elements distributed on a same horizontal plane, two neighboring elements being biased to respective high and low levels.
Claims4
A monolithic DRAM memory that includes a plurality of cells, each respective cell of the plurality of cells including a MOS transistor and a capacitor, the capacitor of each respective cell having a first electrode that contacts a selected region of an underlying substrate of the memory and a second electrode that faces the first electrode and is separated from the first electrode by a dielectric, wherein the second electrode of each capacitor is common to each respective cell of a same row and is covered with an insulator, and wherein the insulator is coated with independent conductive elements distributed on a same horizontal plane, with two neighboring elements being biased to respective high and low potentials.
