Only the higher end "gaming" laptops (i.e. using the Intel Core i7) currently use DDR3. Most laptops are still using DDR2.
DDR, DDR2, SDR, DDR3, DDR4. SO-dimm are for laptops
DDR3 itself, stands for double data rate (revision 3). DDR3 commonly precedes "memory" or "RAM." DDR3 SDRAM is used in most modern computers or laptops, although DDR4 RAM will make its debut in the next year.
Computer uses Memory installed on DIMM Slots on Motherboards.Nowadays different versions of DDR RAMs are used (DDR1, DDR2 & DDR3).Laptops use similar memories (DDR1, DDR2 & DDR3) but in small form of DIMM Sockets called Small Outline Dual Inline Memory Modules (SO-DIMM) memories.
DDR, DDR2 and DDR3 dual channel, DDR3 tripple channel used by Intel X58.

Some examples of Random Access Memory (RAM) include: DDR4: A type of RAM commonly used in desktop computers and high-performance laptops. SDRAM: Synchronous Dynamic RAM, a type of RAM used in older computer systems. LPDDR4: Low-Power DDR4, a type of RAM commonly used in mobile devices like smartphones and tablets. SRAM: Static RAM, faster and more expensive than dynamic RAM, often used in cache memory and embedded systems. DDR3: Another type of RAM commonly used in older desktop computers and laptops.
HP Laptop Memory Guide: How DDR2, DDR3, and DDR4 Impact Performance DDR4 memory in HP laptops offers higher speeds and better energy efficiency than DDR2 or DDR3, which results in faster data transfer, improved multitasking, and better performance for demanding applications like gaming or video editing. etechbuy/blog/hp-laptop-memory-guide-how-ddr2-ddr3-ddr4-impact-performance
DDR3 SDRAM stands for double data rate type three synchronous dynamic random access memory. It is used at the tempory memory a computer needs to operate. It is a faster version of the DDR2 RAM.

ddr3 is a type of ram, not processor
Here's what I found out for you. The DDR3 has 240 pins just like the DDR2, however, they will not be compatible, you will not be able to put a DDR3 into a DDR2 slot. The knotch on the stick of RAM is in a different location so it will not fit. So a new motherboard made for DDR3 will have to be used. They are currently out on the MAC Lite computers but not sure if Microsoft has any on the market yet. The DDR3 will use 1.5V, which is lower than the DDR2 1.8V.
