"e.Digitals process is patented. If CMOS image sensor developers are implementing a cache sequence directly on the transistor matrix that delivers high speed directly to a trapped electron non volatile environment....IMO, they're cheating. They would have to do that utilizing a data environment similar to e.Digital...bypassing status quo environments."

That process started out on-board a device as an internal memory process expanding to the now more popular removable memory process.
