"LL is correct, EDig did not invent flash memory just how to use in a way not used before and not in a manner that would be an inevitable discovery someone might have made had they put all the pieces together as is the case in some patents that were rejected."
It's all about a patented logical overlay orchestrated over a memory matrix(physical cell structure), having novel methods to traverse.
All concepts, including the caching sequence where they pull a modular memory killing a bit stream process, relate directly to a patented background data structure management.
IMO, there are no workarounds, there's a very finite number of ways to lay out data structure, where this is based on a serial process making it that much harder to come up with ideas.
They have the root method everyone else will need.
