COMPENSATING FOR JITTER DURING DDR3 MEMORY DELAY LINE TRAINING

A method for compensating for jitter during DDR3 delay line training may include using a computer or processor to perform the steps of executing a plurality of tests for each one of a plurality of delay values for an interconnect delay between a Double-Data-Rate Three (DDR3) memory controller and a...

Zusammenfassung:A method for compensating for jitter during DDR3 delay line training may include using a computer or processor to perform the steps of executing a plurality of tests for each one of a plurality of delay values for an interconnect delay between a Double-Data-Rate Three (DDR3) memory controller and a DDR3 Synchronous Dynamic Random Access Memory (SDRAM); accumulating a plurality of test results for each plurality of tests for each one of the plurality of delay values; determining a plurality of final test results, where each final test result is associated with an accumulated plurality of test results; and determining a working window edge for the interconnect delay between the DDR3 memory controller and the DDR3 SDRAM utilizing the plurality of final test results.
