Abstract
Apparatuses and methods for creating a constant DQS-DQ delay in a memory device are described. An example apparatus includes a first adjustable delay line configured to provide a delay corresponding to a loop delay of a data strobe signal pathway internal to a memory, a second adjustable delay line included in the internal data strobe signal pathway, and a timing control circuit coupled to the first and second adjustable delay lines and configured to adjust a delay of the second adjustable delay line responsive to output from the first adjustable delay line and the data strobe signal pathway.
