e.Digitals techniques do not have to be flash memory related....the most important part of e.Digitals tech, IMO, is the format overlay of primary memory with logic interface, be it volatile or non volatile. Keep in mind, primary and storage memory are different.

Regarding flash, it would all depend on what you want to save and for how long, while, in e.Digitals case, at the same time utilize it as primary memory.

They have the ability to drive files from a volatile primary memory in the same manner they drive them from non-volatile memory, utilized as primary memory.....exactly.

All kinds of component configuration can be achieved.....depends on what is need.
