It can store 4 bits of data in each prefetch buffer. It also means that it is a ddr2 memory module
DDR1 has a prefetch of 2n, which means it can store 2 bits of data in each prefetch buffer.

No DDR2 and DDR are not compatible and so you can not add DDR2 RAM module in a DDR Slot. Electrical specifications like voltage, signal pinout and even mechanical size and shape of modules are different.
A DDR SDRAM module
No, you cannot use a DDR-2 5300 memory module in a Toshiba Satellite A60 or A65 laptop. This module will not fit into the slot. You can install up to 1GB memory module into the expansion slot, but it has to be DDR memory, not DDR2. Here's what you can use: PC2700 (DDR333) module: 256MB, 512MB or 1GB.
Basically, it is a type of Random Access Memory (RAM) slot, that supports Double Data Rate (DDR) RAM. DDR RAM is said to be twice as fast as Synchronous Dynamic (SD) RAM.
DDR3 memory uses less power. This reduction comes from the difference in supply voltages. The 1.5 V supply voltage works well with the 90-nanometer fabrication technology used in the original DDR3 chips. Some manufacturers further propose using dual-gate transistors to reduce leakage of current. and the benefit is its prefetch buffer, which is 8-burst-deep. In contrast, the prefetch buffer of DDR2 is 4-burst-deep, and the prefetch buffer of DDR is 2-burst-deep. An advantage is an enabling technology in DDR3's transfer speed.
DDR memory is the memory that computers use. A gig of DDR memory is usually around thirty dollars.

DDR, DDR2, SDR, DDR3, DDR4. SO-dimm are for laptops

If you are referring to standard RAM modules for a computer I believe you're looking for "PC1600" DDR ram. Not DDR2 or 3, just plain DDR ram. Hope this helps!
