There are NVRAM types offering a write life of 5000 or so.  These are
fairly elderly, and by now probably relatively cheap.  (Translate = better
profits for the gougers.  We are beginning to know who those are.)

There are later types with much better write life.  I have no idea whether
these have made it into modems as yet.  There was, at one time, a model or
two using battery backed CMOS RAM to get around this limitation.

I can't at this writing - either way.   I operate (as always) on the
assumption of a strictly limited write life, which is safe with either
outcome.
