ABSTRACT:
A semiconductor memory device and an operating method thereof prevent the mal-operation of the semiconductor memory device induced by misrecognizing addresses or data as commands. The semiconductor memory device includes a plurality of input pads, a data information path, a command path, a transfer block configured to transmit signals coupled through the input pads to the data information path and the command path, a command decoding block configured to decode signals transmitted through the command path to verify an inputting of a command, and a transmission control block configured to generate a control signal for controlling the signal transmission from the transfer block to the command path according to the verified result of the command decoding block.
