These are small printed circuit cards (PCC) on which several DRAMS memory chips are placed. Such cards are plugged into the system board of the computer. The SIMM Circuit cards contain several memory chips with contacts placed on only one edge of this PCC whereas in DIMM, it‟s on both sides of the PCC.
There are two types of memory modules :
(i) SIMM : Single Inline Memory Modules
(ii) DIMM : Double Inline Memory Modules
