"destructive read of a ROM"?

[Richard]

Over on comp.terminals someone wrote this about the VT100:

	"The power-on operation does a "destructive" read of the
	ROM-based firmware.  After so many power-ups, the ROM becomes
	unreadable. This was a design issue at the time - the technology
	to fix it did not evolve until the VT200 series."

Is this true?  I've never heard of a ROM being damaged by reading it a
lot.
