Both.

The few modules which read an entire map into memory will also be
limited by available memory and address space, which will affect DCELL
more than CELL or FCELL. However:

1. Memory consumption is determined by whether the module reads the
data as CELL/FCELL/DCELL, not how it's stored on disk.

2. Such modules tend to be algorithmically complex, so execution time
becomes an issue long before memory availability does.
