Is it possible to erase a black memory module?  If yes, how does one accomplish this?  (How do you perform this task?)

Have you reviewed this?: https://control.lionel.com/docs/memory-modules/

*Way* outside my competence area, but ISTM the process is less a matter of *erasing* the black memory module, as it is to overwrite the module with new information. Good luck, in any event!

Just overwrite it.
