A system and method for gate training in a memory system is disclosed. In one embodiment, in a method for calibrating read data strobe gating, a first read command is issued to a memory module. A first DQS gate signal is issued before the beginning of the preamble of a first DQS signal received from the memory module that corresponds to the first read command. A second read command is issued to the memory module such that the preamble of a second DQS signal received from the memory module that corresponds to the second read command is adjacent to the postamble of the first DQS signal. Then, a second DQS gate signal is issued at a preset time after the first DQS gate signal. The second DQS signal is sampled repeatedly to locate the preamble of the second DQS signal.
