RIMM is the term used for a module using Rambus technology. It stands for "Rambus In-Line Memory Module". At times it is wrongly used as an acronym for Rambus Inline Memory Module. Officially, "RIMM" is a term trademarked by Rambus Inc., and it's neither a brand-independent reference nor an acronym like "DIMM". However, many consumers have started to use the term "RIMM" in much the same way people say "Kleenex" for "facial tissue".
RIMM is a memory module that takes up less space inside the computer than the older DIMM module and has different PIN architecture. It is similar to DIMMs using Direct Rambus DRAM memory subsystems.
A RIMM has a 184-pin connector and an SO-RIMM module has a 160-pin connector. An SO-RIMM is smaller and is used in systems that require smaller form factors.
A RIMM module consists of RDRAM chips that are attached using a thin layer of solder. Solder balls on each chip create a metal pathway used to conduct electricity.
