Uniphy DDR3 SDRAM Latency

Hi,

I came across below table in the External memory Interface handbook Volume 3. Could you further explain what are the Even Write, Even Read, Odd Write, and Odd Read?

Thank you!

    Hello,


    I believe these odd write latency and odd read latency are the setting we set in the IP.

    • Odd/even is the number we set. Example, 5 (odd) or 6 (even).
    • write latency is CL = CAS latency
    • read latency is CWL = CAS write latency


    Regards,

    Adzim
