Semiconductor device having memory with ECL gate array.

摘要

A semiconductor device in a single chip comprises a memory (20) having a plurality of memory cells, and an emitter coupled logic gate array (21) for carrying out a predetermined logic operation on a data output from one of the memory cells of the memory and for outputting an output signal having a first amplitude. The memory includes a circuit (251-254) for outputting as the data output a positive phase signal (+DO) and a negative phase signal (-DO) respectively having a second amplitude smaller than the first amplitude.
