Octa rank (2S4Rx4) 3DS memory EMIF

Hello.

 

I am trying to find correct parameters for EMIF calibration stage. Right now, I have HMABAGR7A4R4N-VN SK Hynix RAM. It has 8Rx4(or 2S4Rx4) memory organization. However, I cannot find a template design in Quartus Prime Pro v21.1.0 Build 169. I can see only 2S2Rx4 samples. Does Intel FPGAs support Octa rank memories?

 

Best regards,

Mark

Hi Mark,


You can check the device memory support in External Memory Interface (EMIF) Spec Estimator. Link: https://www.intel.com/content/www/us/en/support/programmable/support-resources/support-centers/emif-spec-estimator.html


You can choose the device that you want to use in Device Family box and select the Memory Format & Topologies.


Regards,

Adzim

Hello Adzim,

 

As far as I understood, there are FPGA that supports quad-rank memories and in order to support octa-rank memory, it must be 3DS that is supported by FPGA like Agilex with the type of 2C4Rx4. Am I correct?

Hi Mark,


I think the architecture of the octa-rank memory can be any of non-3DS and 3DS. But maybe the trend nowadays that want to reduce the area and have a huge density, the manufacturers have designed in that way.
