Abstract
A write circuit for a semiconductor storage device which comprises a data output stage constructed by a composite circuit including at least one MOS transistor logic circuit and bipolar transistor. The Mos transistor circuit operates in response to an input signal to control the on-off states of at least one of the bipolar transistors. The write circuit implements less power consumption.
