Can I individually set refresh periods for each connected memory chip?

Applies to: PL341 AXI DDRII Dynamic Memory Controller

Answer

No.

The assumption is that all memories connected to DMC-34x are of the same type and therefore the same refresh period. This is why there is only a single refresh_prd register and hence all refresh timings for each memory chip connected to DMC-34x are same. It is therefore not possible to set individual chip refresh timing periods.
