1. A read-write circuit for use in a semi-conductor memory device comprising: a write data driver coupled to data lines of the semi-conductor memory device to be activated to drive write data signals onto the data lines during write memory array operations; and a data amplifier coupled in parallel to said data lines, to be activated to accelerate amplification of said write data signals on said data lines during said write memory array operations, as well as to be activated to amplify read data signals on said data lines during read memory array operations.
