Design Considerations: Embedded IA System with DDR3 ECC SO-DIMMs
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.
The levels of a system design that will be covered include:
• Product Planning
• Board Design
• Software Considerations
The goal of this paper is to provide a starting place for the creation of an Intel® architecture (IA) system with ECC SO-DIMM and to help alleviate early questions that system designers may have.
The term “ECC SO-DIMM” is used to describe a newer memory form factor module available on the market. ECC stands for Error Correcting Code while SO-DIMM stands for Small Outline Dual Inline Memory Module. The ECC SO-DIMM is capable of handling a 72-bit data interface. This form factor adds ECC capability to the current SO-DIMM specs and keeps a similar form factor—with changes in pinout.
The ECC SO-DIMM form factor is an alternative solution that is often considered in the embedded market due to the variety of constraints and usage models embedded customers require. The ECC SO-DIMM form factor may help ease or conform to the design constraints that are faced by many embedded applications.
