Thank you for giving me the credit, but I don't think I deserve.

Nah, uni is not back yet, but it doesn't prevent me from learning. That said, you can give me a lecture where you see fit, and I'll just be listening, the way students do to their professor on a regular class.

Oh by the way, it would be really great if you can shed some light for me on the question below which confuses me big time recently:
Last time I read my semiconductor engineering textbook, it says ReRAM is non-volatile by nature. And it occurred to me that all the punters/investors of 4DS are based on one single belief that 4DS is a cutting edge ReRAM technology. But some expert, pardon me couldn't remember who, claims 4DS is NOT non-volatile, because retention measure is not tested and revealed. The question being, how can a technology be ReRAM but not NVM at the same time?

I'm listening to your answer with respectful attention!
