    Latency when crossing pages or rows!

    SaAd_4646326

      It is mentioned that:

           4. A Row is a group of words relevant to the internal memory array structure and additional latency may be inserted by RWDS when crossing Row boundaries - this is

           device dependent behavior, refer to each HyperBus device data sheet for additional information. Also, the number of Rows may be used in the calculation of a

           distributed refresh interval for HyperRAM memory.

           5. A Page is a 16-word (32-byte) length and aligned unit of device internal read or write access and additional latency may be inserted by RWDS when crossing Page

           boundaries - this is device dependent behavior, refer to each HyperBus device data sheet for additional information.

       

       

      What value of latency to use when crossing pages or rows?

       

      Is this the initial latency before RD data out? or it is extra latency between rows or pages?

       

      like RD data as:  [RD data of row1] [Latency] [RD data of row2]
