Abstract
A current control circuit and method for use in a memory device is provided that enhances operational reliability with respect to a test result. The current control circuit controls the current of a main amplifier by controlling current consumed in the test mode and non-test mode. The circuit can include a storage device for storing data and a signal amplifying block including a plurality of main amplifiers for amplifying a data from the storage device based on a read enable signal. A signal amplifying controller is for logically combining word line signals and a test mode signal to output the read enable signal and a test mode determination signal. A current control block is for controlling current of the signal amplifying block based on the test mode determination signal.
