This paper presents a general signal and layout analysis for the two-transistor, one-capacitor DRAM cell. The 2T, 1C configuration enables significantly larger, typically > 3×, raw sense-signal than is achievable in conventional IT, 1C cells. In general, stray capacitances at the capacitor nodes further increase the signal level; an exact analytic formula is derived in this case, including the dependence upon bitline precharge level. With trench technology, the 2T, 1C cell occupies 25-30% more area than a corresponding folded-bitline IT, 1C cell; an implementation employing a buried strap is proposed. Maximization of array density requires multiplexing bitlines to sense amps. © 1994 IEEE
