SIPP RAM or SIPPs combine several RAM chips on a single small circuit card that plugs directly into a memory slot on the motherboard. A SIPP uses pins to connect to the motherboard memory slot.

The advantage of SIPPs is they allow you to plug much more RAM into the motherboard at a time. They usually come in 1 and 4MB capacities. This type of RAM has been replaced by newer technology and is not commonly used today.
