Variants of DIMM slots support DDR, DDR2 and DDR3 RAM. The most common types of DIMMs are: 72-pin SO-DIMM (not the same as a 72-pin SIMM), used for FPM DRAM and EDO DRAM. 100-pin DIMM, used for printer SDRAM.

DIMM is an open standard. DIMM is also copyrighted open standard.
A DDR3 DIMM has three notches - one on each end (which matches the retaining springs on the motherboard socket) - and one offset notch on the row of connector pins - to ensure you insert it the correct way into the socket.

the different notch positions keep someone from installing a DDR DIMM or DDR2 DIMM in the wrong memory slot.
DIMM stands for Dual Inline Memory Module. DIMM slots are the slots on a motherboard that hold the memory modules.
The type of computers that uses 68-pin micro-dimm and 144-pin so-dimm. :P problem... you just got trolled.
240-pin DDR3 dimm is currently the fastest memory. it can support quad, triple, or dual channels or be installed as a single dimm. it has an offset notch father from the center than a ddr2 dimm
There is a notch that prevents installation, even though the modules are the same size and have the same number of pins. Notch position between DDR and DDR2 are diferent. Also, the memory socket on a motherboard is diferent for all types of memories. If the memory socket is design for DDR you can't put any other memory type but DDR and so for all other types.
SIMMs and DIMM are both type of main memory modules. One in single-sided (SIMM) and one is double-sided (DIMM).
