A '''SO-DIMM''' (pronounced "so dim" {{IPAc-en|ˈ|s|oʊ|d|ɪ|m}}, also spelled '''SODIMM''') or '''small outline DIMM''', is a smaller alternative to a DIMM, being roughly half the physical size of a regular DIMM. The first SO-DIMMs had 72 pins and were introduced by JEDEC in 1997.<ref name="auto"/><ref>{{cite web | url=https://www.jedec.org/standards-documents/docs/module-444 | title=72 Pin DRAM SO-DIMM &#124; JEDEC | access-date=2023-11-09 | archive-date=2024-09-17 | archive-url=https://web.archive.org/web/20240917213306/https://www.jedec.org/standards-documents/docs/module-444 | url-status=live }}</ref><ref>{{Cite web|url=http://archive.org/details/completeidiotsgu00fult|title=The complete idiot's guide to upgrading and repairing PCs|first=Jennifer|last=Fulton|date=November 9, 2000|publisher=Indianapolis, IN : Alpha Books|via=Internet Archive}}</ref> Before its introduction, many laptops would use proprietary<ref>{{Cite web|url=https://books.google.com/books?id=u2cfcECC1dwC&dq=%2260-pin%22+memory+card&pg=PP36|title=PC Magazine|last1=Jones|first1=Mitt|date=December 25, 1990|publisher=Ziff-Davis Publishing Company|via=Google Books|access-date=February 4, 2024|archive-date=September 17, 2024|archive-url=https://web.archive.org/web/20240917213428/https://books.google.com/books?id=u2cfcECC1dwC&dq=%2260-pin%22+memory+card&pg=PP36#v=onepage&q=%2260-pin%22%20memory%20card&f=false|url-status=live}}</ref> RAM modules which were expensive and hard to find.<ref name="auto"/><ref>{{cite book | url=https://books.google.com/books?id=O0FTac_k7CIC&dq=laptop+proprietary+sodimm&pg=PA36 | title=Peter Norton's New Inside the PC | isbn=9780672322891 | last1=Norton | first1=Peter | last2=Clark | first2=Scott H. | date=2002 | publisher=Sams }}</ref>

SO-DIMMs are often used in computers that have limited space, which include [[laptop]]s, [[notebook computer]]s, small-footprint personal computers such as those based on [[Nano-ITX motherboard]]s, high-end upgradable office [[Computer printer|printers]], and [[networking hardware]] such as [[Router (computing)|routers]] and [[Network-attached storage|NAS]] devices.<ref>{{cite web |author=Synology Inc. |title=Synology RAM Module |url=https://www.synology.com/en-global/products/Synology_RAM_Module |work=synology.com |access-date=2022-03-23 |archive-date=2016-06-02 |archive-url=https://web.archive.org/web/20160602224830/https://www.synology.com/en-global/products/Synology_RAM_Module |url-status=live }}</ref> They are usually available with the same size data path and speed ratings of the regular DIMMs though normally with smaller capacities.
