"Expanded Memory was a trick invented around 1984 that provided more
memory to byte-hungry, business-oriented MS-DOS programs."

So expanded memory was developed around the same time that DOS 3.0 did.
However, there's nothing to indicate that it needed DOS 3.0 to run, it was
a separate hardware driver.

"Originally, it was called QEMM-386"

QEMM required a 386 microprocessor, which came out in 1985, a year after
DOS 3.0. QEMM worked according to specifications of the 386 proccessor,
not according to anything new that DOS 3.0 had, unless you can think of a
way support for high-density (1.2 MB) floppy disks and 32 MB hard disks
affects extended memory management.
