A SO-DIMM, or small outline dual in-line memory module, is a type of built using integrated circuits.
SO-DIMMs (also written SODIMMs) are a smaller alternative to a , being roughly half the size of regular DIMMs. SO-DIMMs are often used in systems which have space restrictions such as , small footprint PCs (such as those with a ), high-end upgradable office , and like .
The main difference between SIMMs and DIMMs is that DIMMs have separate electrical contacts on each side of the module, while the contacts on SIMMs on both sides are redundant. Another difference is that standard SIMMs have a 32-bit data path, while standard DIMMs have a 64-bit data path. Since 's Pentium has (as do several other processors) a 64-bit width, it requires SIMMs installed in matched pairs in order to complete the data bus. The processor would then access the two SIMMs simultaneously. DIMMs were introduced to eliminate this practice.
