Is it OK to use DDR3 mixed configuration both on-board and SODIMM for i.MX6?

[t-iishii]

Hi community,

My customer plan to use DDR3 DIMM module as a extended memory for i.MX6 products.

Of the total 4 GByte of memory, 2 GByte is prepared on-board and the rest are prepared by SO-DIMM.

Does anyone have an use case with such a configuration?

Best regards,

Ishii.

Hi Ishii

I do not know such designs but seems it is possible following

layout recommendations given in sect.3.5.5 4-Gigabyte recommendations

i.MX6 System Development User’s Guide

Hello igor

Thank you for your quick response.

If it use 4GByte recommendation design, it can use different timing parameter for each Chip Select?
