An address buffer circuit is used in a memory device, for example in an EPROM device, and enables high speed testing of the memory device. The address buffer circuit can output "1" or "0" from both a positive output terminal and a negative output terminal when an input word address signal having a signal level different from the usual signal level is applied to an input of the address buffer circuit, so that a plurality of word lines can be selected at a time.
