Abstract
A method of operating a semiconductor memory device including a plurality of pins configured to transfer data and signals from/to an outside of the semiconductor memory device, a memory cell array and a control logic circuit to control access to the memory cell array. A write command synchronized with a main clock signal and data synchronized with a data clock signal are received from outside of the semiconductor memory device, the data is stored in the memory cell array based on a frequency-divided data clock signal, data is read from the memory cell array in response to a read command and a target address received from the outside of the semiconductor memory device, and the read data is transmitted to the outside of the semiconductor memory device selectively with a strobe signal generated based on a frequency of the main clock signal.
