Abstract
Techniques provided herein compensate for an internal and external timing skew between a data strobe (DQS) and a clock (CLK), by: executing at least one write leveling initialization procedure (WLInit) that uses a mode-register-write (MRW) command to synchronize a timing between a data strobe (DQS) with a clock (CLK) based upon capture of an internal write command. Internal and external timing skew is identified based upon the WLInit. The internal timing skew is skew caused internal to a memory device and the external timing skew is skew caused external to the memory device. A timing between the DQS and the CLK is adjusted based upon the internal and external timing skew.
