Hello,
I am looking for more details on the exact behavior of the SDRAM controller of the EMIF.
In particular, I would like to understand if really all read/write accesses start with an ACT command, or if the memory controller is first checking if the row/bank is already open and then proceeds to the read/write operation skipping the ACT.
Also it's not clear to me when an open row is closed since auto precharge is not used.
Any information will be appreciated.
Mathieu
