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 8):
The method according to  claim 1 , further comprising:\n prior to running the coarse calibration test, setting, by the DDR memory controller, the first number of cycles set in the tunable write delay setting to a first value within a parameter setting of an allowable range of write delays and the second number of cycles set in the tunable write delay setting to a second value within the parameter setting of an allowable range of read delays.
