Abstract
A read circuit includes a current load circuit configured to supply a load current from a power source to a first input and a second input; a first discharge circuit configured to discharge potential of the first and second inputs to a ground level; an equalization circuit configured to equalize the potential of the first and second inputs; a differential circuit configured to receive the first and second inputs as differential inputs, and to output a first output and a second read output as differential outputs; and a second discharge circuit configured to discharge potential of the first and second read outputs to the ground level.
