ABSTRACT:
A mode selecting circuit for selecting a single operational mode in a semiconductor memory device having a plurality of operational modes. Instead of using an additional masking process, the present invention uses mode selecting pads, wherein a mode selecting pad is bonded to the terminal of the power source so as to select a mode in the final assemblying stage of the manufacturing process, so that the process is simplified and the yield rate is increased.
