A technicality, but this isn't quite accurate.

Copyright law generally distinguishes not between what is or isn't
copying, but between what is or isn't an *infringing* copy.  17 USC 117
doesn't say that copying a program in RAM isn't copying, but that it's
a non-infringing copy, if performed under certain circumstances (the
normal execution of a program, by or authorized by the lawful owner of a
copy of the program).

A more interesting instance is the so-called home recording provision,
section 1008.  In this case, the exemption doesn't state that the copy is
legal or othewise, but that it cannot be prosecuted:

    17 USC 1008  Prohibition on certain infrigement actions.

    No action may be brought under this title alleging infringement of
    copyright based on the manufacture, importation, or distribution of
    a digital audio recording device, a digital audio recording medium,
    an analog recording device, or an analog recording medium, or based
    on the noncommercial use by a consumer of such a device or medium
    for making digital musical recordings or analog musical
