Interconnect Noise Analysis For Megabit Dram'S

Abstract

Analytical noise modeling of the bit line coupling analysis for various DRAM architectures has been developed. Intrabit and interbit line coupling for true folded, interdigitated, and twisted architectures are analyzed. Analytical equations for the noise-to-signal ratio are derived based on the charge conservation and the current continuity equations. The time-dependent differential equations for twisted architectures are presented. The analytical expressions provide insight into the charge redistribution when the word lines turn on. The topology for array noise extraction in SPICE circuit simulation is presented. SPICE simulations are found to be in good agreement with the analytical results.
