Abstract
Provided herein may be a semiconductor memory device and a method of operating the same. The semiconductor memory device may include a delay code determining unit configured to output a final delay trim code reflecting process, voltage and temperature (PVT) conditions of the semiconductor memory device, using an internal clock generated for a reference time and a delay circuit configured to reflect a delay of a data line on a clock signal in response to the final delay trim code.
