Abstract

PURPOSE:To obtain a semiconductor device having a largecapacity memory in combination with an analogue circuit and still operable at high speed with low noise, by providing a memory consistuted by a MOS transistor and an analogue circuit within one chip. CONSTITUTION:A semiconductor chip 100 has a memory 10 constituted by a MOST and an analogue circuit 20 constituted by an analogue/digital converting circuit, an operational amplifier etc. Since the memory constituted by the MOST occupies a small area and exhibits low power consumption, the memory of large capacity can be mounted together with the analogue circuit on the same chip. Accordingly, length of interconnection connecting between the memory and the analogue cicuit can be shortened and parasitic capacity of the interconnection is decreased substantially. As a result, a number of interconnections can be decreased and noise caused upon simultaneous change of potential or current can be decreased. ln this manner, a semiconductor device having a large-capacity memory in combination with an analogue circuit and still operable at high speed with low noise can be obtained.
