Abstract

PURPOSE:To obtain a logic circuit with less dispersion of output of MTR, by providing a voltage clamp means between the base or collector and power supply terminal, to a multi-emitter transistor MTR. CONSTITUTION:The collector of an MTR10 is connected to a ground point GND of the circuit via a series connection of resistors R1, R2 constituting a current detection circuit, the base is connected to the connection point of the resistors R1, R2 and the GND via a clamp diode D1, and the base of a bipolar transistor TR11 is connected to the collector of the MTR10, and the collector of TR11 is connected to the GND. The emitters of the MTR10 are provided with lines 20-22, 20'-22' receiving the noninverting and inverting outputs of three buffer circuits B, for example, and the circuits B are connected to lines 20, 21', 22', for example, depending on the content of code. Further, the word line W connected to the memory cell m is connected to the emitter of TR11. Thus, the dispersion in MTR can be reduced.
