Abstract
PURPOSE:To read a bipolar C-MOS type RAM or the like at high speed by constituting a cascade circuit connected to a complementary common collector line of a differential amplifier and two sets of emitter follower circuits. CONSTITUTION:A reading signal from a selected memory cell is transformed to a current signal to a complementary common line (r), the inverse of (r) by corresponding sense amplifiers SA0-SA3. The change of these current signals is connected to the base of transistors T9, T8 constituting the differential amplifier of the cascade circuit of a data output buffer DOB, inverted and amplified and negative fed back to the collector line (r), the inverse of (r) through the emitter follower circuit constituted of transistor T7, T10, resistances 2, 5 and constant current sources IS4, IS6. Thereby, the charging and the discharging operations of the collector line according to the inversion of the reading signal are shortened to attain the reading speed at high speed.
