That depends on the amount of time you need for refresh. Generally you need to refresh every row with 64ms or thereabouts, depending on the size. Which SDRAM are you using?

Hello

I use this SDRAM : IS42S16160D-7TL 256M(16Mx16).

Do you know how to calculate the time required to unload the data (256 Mbites) of the SDRAM to the CPLD.

Thank you
