PURPOSE:To enable the high-speed sense-operation of read-out data by constituting a sense-amplifier with a signal input differential-connection bipolar transistors and grounded base transistors connected to the collectors of the differential-connection transistors. CONSTITUTION:A voltage-to-current transducing means 1 consisting of bipolar transistors TRQ70, Q71 of the differential-connection is included in the sense- amplifier. The transducing means is composed of NPN TRs Q70, Q71 of the defferential-connection and NPN TRs Q72, Q73 of the cascade-connection. A miller effect is hardly generated since the transducing means 1 is made to be the cascade-connection of bipolar transistors in such a manner. Thus, the delay-time due to a signal source resistance and an input capacitance is remarkably shortened since the input capacitance of the means is made very small. |
