Abstract
A memory system includes a memory and a controller for providing the memory with a data strobe signal; and data synchronized with an internal data strobe signal, wherein the controller includes a signal generator for generating the data strobe signal, an inverter for selectively outputting one between a non-inverted data strobe signal having the same phase as the data strobe signal and an inverted data strobe signal having an inverted phase to the phase of the data strobe signal based on an inversion signal, a delayer for delaying the inverted data strobe signal or the non-inverted data strobe signal based on a delay signal and outputting the internal data strobe signal, and a trainer for performing a verification operation on the synchronized data and generating the inversion signal and the delay signal based on the verification operation result.
