Animal experiments have provided strong evidence for the involvement of a tyrosine kinase receptor for type II collagen, discoidin domain receptor 2 (DDR2), in the pathogenesis of OA. Sunk et al.

Designers today face the challenge of integrating DDR2 memory devices onto the same PCB while using the correct termination to ensure signal quality. This is applicable to any embedded platforms ...

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.

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 ...
