A current sense circuit with fast response for sensing a current input from a current source such as a memory cell, comprising a first amplifying means and a second amplifying means coupled to a first transistor and a second transistor, respectively. The first transistor is smaller in size than the second transistor and the reference voltage of the first amplifying means is slightly larger than the reference voltage of the second amplifying means. A load is coupled to the drain of the first transistor.
