Single In-line Memory Module
Jump to user comments
storage (SIMM) A small circuit board or substrate, typically
one or both sides and a single row of pins along one long
edge. Several SIMMs are mounted with their substrates at
right-angles to the main circuit board (the
motherboard).
This configuration allows greater packing density than direct
motherboard. In 1993 one SIMM typically held one or four
megabytes, by early 1997 one could hold 8, 16, or 32 MB.
