ABSTRACT:
A semiconductor memory device with low power consumption and improved transfer rate of an input/output buffer at reduced manufacturing cost is provided. Thick-film transistors are used for a memory cell array33, a row decoder30, and a sense amplifier32, surrounded by a bold broken line. Thick-film transistors having a threshold voltage lower than the aforementioned transistors are used for input buffers11to13and an input/output buffer26, surrounded by a bold line. Thin-film transistors are used for a clock generator16, a command decoder17, a mode register18, a controller20, a row address buffer and refresh counter21, a column address buffer and burst counter22, a data control circuit23, a latch circuit24, a DLL25, and a column decoder31.
