What are ECC SO-DIMMs? How do I design with them in my platform? If these are some of the questions you have when the term “ECC SO-DIMM” comes up, then this paper may be for you. Since the ECC SO-DIMM form factor is an alternative solution that is often considered in the Embedded market, this paper will look at all the aspects of preparing for and designing an Embedded system with ECC SO-DIMMs instead of using the traditional DDR3 UDIMM or SO-DIMM memory. Each level of a system design will be addressed in this paper.
