A semiconductor memory test circuit comprises a current mirror circuit including a reference side current path composed of a series connection of alternating p channel transistors and n channel transistors and an output side current path composed of a series connection of alternating p channel transistors and n channel transistors, an output signal for electrode of paired memory cells and a balance potential output signal for sense amplifier, required for a semiconductor memory test, being derived from the output side current path. The current mirror circuit includes a first output side current path and a second output side current path, the balance output for sense amplifier is derived from an output of the first output side current path and the output signal for electrode of paired memory cells is derived from an output of the second output side current path.
