[[File:168 pin and 184 pin DIMM.jpg|thumb|Two types of DIMMs: a 168-pin [[SDRAM]] module (top) and a 184-pin [[DDR SDRAM]] module (bottom). The SDRAM module has two notches (rectangular cuts or incisions) on the bottom edge, while the DDR1 SDRAM module has one. Also, each module has eight RAM chips, but the lower one has an unoccupied space for the ninth chip; this space is occupied in [[ECC_memory|ECC]] DIMMs.]]

A '''DIMM''' ('''Dual In-line Memory Module''') is a popular type of [[memory module]] used in computers. It is a [[printed circuit board]] with one or both sides (front and back) holding [[DRAM]] [[integrated circuit|chip]]s and [[Pin (electronics)|pin]]s.<ref name="GeeksforGeeks 2020 e240">{{cite web | title=What is DIMM(Dual Inline Memory Module)? | website=GeeksforGeeks | date=2020-04-15 | url=https://www.geeksforgeeks.org/what-is-dimmdual-inline-memory-module/ | access-date=2024-04-07 | quote=In the case of SIMM, the connectors are only present on the single side of the module...DIMM has a row of connectors on both sides(front and back) of the module | archive-date=2024-04-07 | archive-url=https://web.archive.org/web/20240407102508/https://www.geeksforgeeks.org/what-is-dimmdual-inline-memory-module/ | url-status=live }}</ref> The vast majority of DIMMs are manufactured in compliance with [[JEDEC memory standards]], although there are proprietary DIMMs. DIMMs come in a variety of speeds and capacities, and are generally one of two lengths: PC, which are {{Convert|133.35|mm|in|2|abbr=on}}, and laptop (SO-DIMM), which are about half the length at {{Convert|67.60|mm|in|2|abbr=on}}.<ref name=":0" />
