Abstract
A semiconductor device includes a drive control circuit and a write control circuit. The drive control circuit generates a pre-drive control signal and a drive control signal based on a latch command and generates a pattern drive control signal based on a pattern latch command. The write control circuit stores drive data generated from data inputted based on the pre-drive control signal and the drive control signal or stores the drive data driven to a predetermined logic level based on the pattern drive control signal.
