ROM, RAM, EEPROM, SSD and similar are all
non-magnetic storage devices, so static magnetic fields aren't a problem. A rapidly fluctuating one
might be, but it would have to be an
extremely strong one. On the order of an MRI superconducting magnet say, not a feeble fridge magnet.
Even for traditional magnetic disk storage, a pretty strong field is needed to affect its storage. A laboratory degausser would do, so somewhat less strong than an MRI. But again, a fridge magnet or similar won't have any effect. A magnetised screwdriver would have a lesser field than even a fridge magnet.
So when are magnets an issue around computers? Two instances off the top of my head. Old-style CRT displays can be discoloured semi-permanently if you accidentally (or maliciously!) magnetise the colour mask. And laptops often use a magnetic lid switch to sense when it is closed or open, so sticking a magnet in the wrong place fools the laptop into sleeping -- you can often see this if you stack one open laptop directly on top of another closed one.
