Accessing rows in bank

Hi @ all,



I am trying to implement a SDR/DDR SDRAM controller.



My question:



Is it possible to access (write or read) two different rows in one bank at the same time ? I could not find that situation described in any of those papers I read (for example Micron, Infineon).



Thank you for your help.

Two rows are not ACTive at one time in standard SDRAM in a single Bank & Rank. To access a new row, the first must go through a PREcharge before the other can be ACTivated to perform a read or write.
