Double-Data-Rate-Two Synchronous Dynamic Random Access Memory (DDR2 SDRAM) is the memory technology used for high speed data transfer. This class of memory technology has 4n pre-fetch architecture and ...

The emerging DDR3 memory standard will extend the performance range of DDR memories considerably, while maintaining some amount of backwards compatibility with the existing DDR2 memory standard. It is ...

This is because the pin configuration for a DDR3 RAM is different from that of DDR2 or DDR4, this is why you need to make sure that the RAM you buy must be compatible with your computer.

What is it? It is the amount of data transferred in one pass. It also determines how fast RAM is. For example, DDR2 RAM has a prefetch rate of 4n and both DDR3 and DDR4 RAM have the same prefetch ...

It’s based around an AT91SAM9G25 which is an ARM9 chip running at 400MHz. Paired with the DDR2 RAM (in 128 or 256 meg options) to the left, the board runs Linux and runs it well. After the ...
