Dual DIMM DDR2 SDRAM memory interface design guidelines

Posted: 05 Mar 2007 ?? ?Print Version ?Bookmark and Share

Keywords:DIMM? DDR memory? DDR2? SDRAM? single-DIMM?

This paper looked at a single-DIMM and a dual-DIMM DDR2 SDRAM memory interface and examined the effects on the signal quality due to the second DIMM. The simulations and board measurements were taken using the OCT feature on the FPGA (25-ohm OCT) and the ODT feature on the DDR2 SDRAM memory and using these simulations and experimental results, you dan draw conclusions for the optimum design guidelines for the best signal quality.
