I'm using pgfplots to plot some graph of data I stored in a file (a lot of data points). If I charge the bibtex package, I obtains the following error:

TeX capacity exceeded, sorry [main memory size=300000].

Is there any kind of incompatibility between biblatex and pgfplots?

Incompatibility reasons for packages usually does not show itself with memory problems.

Your problem is due to the fact that biblatex requires more memory space than usual bibtex packages, such as natbib. You should know that biblatex is a big package.
You should simply increase your memory size which is dependent on your distribution.

The manual for pgfplots is useful as it has a section regarding this issue. See section Memory Limits or search around for increasing the memory size for your distro, MikTeX, TeXLive, MacTeX, etc.
