Abstract
A semiconductor memory device capable of determining an operation mode by using states of data pins, and an operation mode determining method for the same are disclosed. The semiconductor memory device includes at least one MRS input pad, at least one data input pad, and an operation mode determining circuit. The operation mode determining circuit generates an operation mode determining signal, when an MRS command input through the MRS input pad corresponds to a predetermined MRS command and data signals input through the data input pad or pads include a predetermined combination. Accordingly, the efficiency in the manufacturing and producing processes may be improved by determining the operation mode of the semiconductor memory device in a module assembly process.
