PURPOSE:To improve operation margin without increasing a cell area regarding a multi-emitter bipolar memory by providing a fixed current source function between a low potential word line (hold line) and an emitter at the hold side. CONSTITUTION:The title device has a memory cell for crossing and connecting a collector and a base of two multi-emitter transistors with a plurality of emitters mutually, for connecting one emitter to a bit select line and for connecting the other emitter to a low potential word line (hold line). A high resistance film 13 is provided between a low potential word line 17 and an emitter electrode 12 connected to the low potential word line. |
