single inline package (chip design) (SIP)
The Single Inline Package(SIP) is a classic design for memory chips and other integrated circuits. This design is space-saving because the components are arranged vertically.
SIPs have only one strip with connection pins, whose standard spacing is 2.54 mm. The connection pin is marked by a notch. Single Inline Packages are in a way the predecessors of Single Inline Memory Modules( SIMM). SIPs were always single discrete memory modules and were equipped with plug-in feet instead of the contact strip used in SIMMs. There are various socket variants for SIP packages.
