DIMM

Short for Dual In-line Memory Module, DIMM is a type of circuit board that holds memory chips. DIMMs have a 64-bit path because of the Pentium Processor requirements. Because of the new bit path, DIMMs can be installed one at a time, unlike SIMMs on a Pentium that would require two to be added. Below is an example image of a 512MB DIMM memory stick.

SO-DIMM is short for Small Outline DIMM and is available as a 72-pin and 144-pin configuration. SO-DIMMs are commonly utilized in laptop computers.

Some of the advantages DIMMs have over SIMMs:

  1. DIMMs have separate contacts on each side of the board, thereby providing twice as much data as a single SIMM.
  2. The command address and control signals are buffered on the DIMMs. With heavy memory requirements this will reduce the loading effort of the memory.
