Definition
-
A SIMM, or single in-line memory module, is a memory module on a printed circuit board containing RAM memory. RAM, or random access memory, is a temporary form of computer data storage. SIMM modules were widely used in computers from the early 1980s through the late 1990s but were later replaced by DIMMs, or dual in-line memory modules. SIMMs differ from DIMMs in that SIMMs house redundant contacts on both sides of the module. SIMM modules also use a 32-bit bus, or data channel. DIMMs utilize a 64-bit bus.
Process
-
SIMM modules connect to the computer via a memory socket on the motherboard, or primary circuit board. SIMM modules must be inserted into the socket at an angle, and then rotated into the proper position. To remove a SIMM module, the clips attached at either end of the module must be turned to one side. The module can then be tilted back at an angle and removed.
