Abstract
Provided is a method of operating a controller to control an operation of a semiconductor memory device. The method includes: determining a minimum pass tapped delay of the semiconductor memory device based on a first offset; determining a maximum pass tapped delay of the semiconductor memory device based on a second offset; and determining a tapped delay of the semiconductor memory device based on the determined minimum pass tapped delay and the determined maximum pass tapped delay.
