This paper describes a low voltage swing BUS driver using FCSR (Feedback Control Swing voltage Reduction) which can control BUS swing voltage within a few hundred of mV. It is proposed to reduce power consumption in On-chip interface, especially for MDL(Merged DRAM Logic) architecture which has wide and large capacitance BUS. FCSR operates on differential signal dual BUS and on precharged BUS with block controlling function.
We modeled driver and BUS to scale driver size automatically when BUS environment is variant. We also modeled coupling capacitance noise of neighborhood lines (crosstalk) which operate on odd mode with parallel current source to analysis crosstalk effect in the victim line according as voltage transition in the aggressor line and environment in the victim line.
