Everything I need to know is in the last announcement.

4DS Memory Limited (ASX:4DS) (4DS or the Company) is pleased to announce that imec, its development partner, hasfabricated functional 300mm wafers on the same multi-million dollar state-of-the-art production equipment used by high volume manufacturers of memory.

As previously reported the Board believes 4DS remains on track and is confident that detailed testing and analysisover the balance of Q1 2019 at 4DS’ facilities, will provide invaluable data to refine the fabrication processes required to produce a megabit test chip during 2019.

Good Luck with WBT, hope the Directors don't sell another 10 Million shares.
