The Supercharger has a total of 6K RAM in three 2K chunks.  In multiload
games, I believe 2K is preserved and 4K is swapped in and out.  Otherwise
you can load and use the full 6K at once, I assume through some form of
banking since the 2600 can only read 4K at a time (though I heard once that
some weird custom addressing scheme could allow for 6K without banks).

Not for later sessions, just for one play session but multiple loads.  When
loading from tape, as discussed above, you can determine specifically which
chunks of memory will get overwritten and which will be left alone, a very
powerful feature.

Theoretically, then, you can have a game with hundreds of waves in separate
program modules and preserve your score, inventory, and other details as
you progress, the equivalent of hundreds of K of banked ROM.  It's just not
instantly accessible...
