Abstract:
A double data rate (DDR) memory controller writes a test pattern to a location in a DDR memory for a coarse calibration test, delayed by a first number of cycles set in a tunable write delay setting. The DDR memory controller simulates a single data rate (SDR) mode for the coarse calibration test by only comparing every other read beat of the test pattern read from the DDR memory, delayed by a second number of cycles set in tunable read delay setting, wherein every other read beat is latched for a full cycle. The DDR memory controller, responsive to every other read beat of the test pattern matching an expected result, sets the first number of cycles and the second number of cycles as coarse calibration settings for a DRAM.

Claim (Index 12):
The computer system according to  claim 11 , wherein the stored program instructions to simulate, by the DDR memory controller, the SDR mode for the coarse calibration test by only comparing every other read beat of the test pattern read from the DDR memory, delayed by the second number of cycles set in the tunable read delay setting, wherein every other read beat is latched for a full cycle further comprise:\n program instructions to simulate, by the DDR memory controller, the SDR mode for the coarse alignment test by only comparing every odd beat of the test pattern read from the DDR memory, wherein a programmable data bus delay is set to align with a data strobe signal for latching data read from the DDR memory, wherein the data strobe signal latches data read from the DDR memory on a falling edge of the data strobe signal.
