Abstract

PURPOSE:To enable high speed operation with low power consumption, by constituting the load with a parallel circuit of FETs having different gm. CONSTITUTION:A load L is constituted with a parallel circuit of an FET-Q1 which is of P channel type reverse to an MISFET-T for memory and has comparatively smaller gm and a Q2 which is of the same type at the Q1 and has comparatively greater gm. The Q1 is turned on with the power source line V2 at all times, and when the signal on an address line A is at ''1'', the T in a cell M turns on, the output of a bit line B is at ''0'', the output of an inverter 1 is at ''1'' and the Q2 turns off. When the address signal is at ''0'', the T turns off, and the output of the line B changes from ''0'' to ''1''. In this case, the output of the circuit 1 changes from ''1'' to ''0'', the Q2 turns on and the output of the line B becomes ''1'' rapidly.
