Abstract: A method of training command signals for a memory module. The method includes programming a memory controller into a mode wherein a column access strobe is active for a single clock cycle. The method then programs a programmable delay line of the column access strobe with a delay value and performs initialization of the memory module. A read command is then sent to the memory module. A number of data strobe signals sent by the memory module in response to the read command are counted. A determination is made whether the memory module is in a pass state or an error state based on a result of the counting.

Abstract: A method of training a command signal for a memory module. The method includes programming a memory controller into a mode wherein a single bit of an address signal is active for a single clock cycle. The method then programs a programmable delay line of the address signal with a delay value and performs initialization of the memory module. The memory module is then placed in a write leveling mode. A write leveling procedure is then performed and a response thereto is determined from the memory module. A determination is made whether the memory module is in a pass state or an error state based on the response.
