An SO-DIMM, SODIMM, or small outline dual in-line memory module, is a type of computer memory built using integrated circuits. SO-DIMMs are a smaller alternative to a DIMM, being roughly half the size of regular DIMMs. SO-DIMMs are often used in systems that have limited space, such as notebooks, small-footprint personal computers (such as those with a Mini-ITX motherboard), high-end upgradable office printers, and networking hardware like routers and NAS devices.〔(【引用サイトリンク】title=Synology RAM Module )〕 == Visual identification == Most types of SO-DIMMs can be recognized at a glance by the distinctive notches that “key” them for different applications:〔(【引用サイトリンク】 Are DDR, DDR2 and DDR3 SO-DIMM memory modules interchangeable? )〕 * 100-pin SO-DIMMs have two notches. * 144-pin SO-DIMMs have a single notch near the center. * 200-pin SO-DIMMs have a single notch nearer to one side. The exact location of this notch varies (read below). * 204-pin SO-DIMMs (DDR3) have a single notch closer to the center than on 200-pin SO-DIMMs. * 260-pin SO-DIMMs (DDR4), wide and high, making them wider than DDR3 SO-DIMMs, with a single notch after pin 144. * 260-pin SO-DIMMs (UniDIMM), wide and or high, with a single notch placed differently than on DDR3 SO-DIMMs. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「SO-DIMM」の詳細全文を読む スポンサード リンク
