Octa rank (2S4Rx4) 3DS memory EMIF - 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?

But maybe the trend nowadays that want to reduce the area and have a huge density, the manufacturers have designed in that way.

Am I correct? Best regards, Mark Replies: Re: Octa rank (2S4Rx4) 3DS memory EMIF 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.
