Is it possible to keep interrupts active during flash program/erase?

In my application I'm sampling a 50Hz voltage at 300Hz in a timer interrupt.

My application is able to alter a part of the flash memory to save parameters. But during during flash write/erase activity the CPU stalls and my sampling gets interrupted (and my RMS calculations goes wrong).

Is it possible to move my sampling interrupt function to RAM or would it still stall during flash write/erase activity?
