ABSTRACT:
A current control circuit for a dynamic random access memory device which has a bit line sense amplifier for sensing and amplifying bit data on a bit line, and a data bit clamping circuit for supplying current to the bit line sense amplifier. The current control circuit is adapted to control the current from the data bit clamping circuit to the bit line sense amplifier. The current control circuit comprises a first path switching circuit for forming a current path from the data bit clamping circuit to the bit line sense amplifier during a refresh operation, a second path switching circuit connected between the first path switching circuit and the data bit clamping circuit, for opening/closing the current path, and a path controller for generating a current control signal in response to an address signal and supplying the generated current control signal to the second path switching circuit.
