Yes, the whole screen data is in RAM.
You can download the Gamebuino library from here to see how it works:

(It's the best documentation you can have)
In "Display.cpp" you have all you need in regard to your question:

Also the user manual for the PCD8544 driver chip is here:

Memory is internal but there is no way of accessing it or even syncing to the vertical refresh

Great !
Thank you for all your responses, and specially the pdf link.
The LCD 5110 seem to be a fun chip.
