PROBLEM TO BE SOLVED: To realize a semiconductor integrated circuit configuration in which a level shifter circuit provided at a prestage of an output driver part is eliminated. SOLUTION: This semiconductor memory circuit consists of a current mirror amplifier 2 which uses an internal power supply to operate and amplifies the data read onto a data bus 1 from the memory cell, a differential amplifier 3 which uses an external power supply to operate, further amplifies the data of an internal power supply level outputted from the current mirror type amplifier 2, a data latch circuit 4 for latching the data outputted from the differential amplifier 3 in accordance with a data latch signal DATAL, and an output driver 5 for outputting the data outputted from the data latch circuit 4 to the outside.
