SIPPs
One of the first module forms of DRAM, the SIPP (single inline pin package) is a printed circuit board with individual DRAM chips mounted on it, shown in Figure 7.2. Physically, a SIPP module looks like a rectangular card with a single row of pins along one edge. The SIPP had a very short time in the sun, due to the fragile nature of these pins.

CAUTION
SIPPs have a row of pins along one side. These pins are easily broken, and care should be taken to avoid damaging them during installation.
