Abstract:
A semiconductor device in which a DRAM and a logic part are integrated into one chip: comprisingan external input terminal for supplying the logic part with a signal necessary for the logic part to control the DRAM; an external data input terminal for supplying the logic part with input data; an external data output terminal for outputting the output data from the DRAM to the outside; a level shifter converting the operation voltage level of a DRAM control signal and the input data which are output from the logic part, and outputting the DRAM control signal to the DRAM, and an interface circuit controlling the input data output from the level shifter and the output data output from the DRAM by an interface control signal supplied from the DRAM, outputting the input data to the DRAM, and outputting the output data to the external data output terminal and the logic part; wherein the logic part operates with a low voltage power supply.
