Title: Sense amplifier circuit
Inventor: SATOU TAKASHI
IPC: G11C11/409
Filed: 1977-10-24
Abstract: PURPOSE:To realize the high speed and high sensitivity for the dynamic FF circuit by applying the defferential input signal also to driving MISFET of the FF circuit. CONSTITUTION:MISFET Q1, which is provided to MISFET Q2, Q3, and their common source receiving application of the differential input singal from the memory cell and controlled by clock pulse phi1, forms buffer amplifier BA. The output signals are applied to the gates of load Q13 and Q15 plue dirving Q16 and Q14 of the first inverter circuit (MISFETQ13 and Q14) and the second inverter circuit  (MISFETQ15 and Q16) which form sense amplifier SA. Accordingly, the output of the in verter circuit is determined by the geometeical conductance between Q13/Q15 and Q16/Q14 caused by the level difference of the input signal, and the conductance difference becomes large between the both inverter circuits at the instant when clock phi2 features high livel. As a result, the level lowering of the storage charge can be prvented with no reduction of the conductance of load Q3 or Q15. Thus, the high- speed and assured charging is ensured for output capactiy C3 or c4 of SA.
