I attended the AGM last week - gave me a bit more confidence that there is still a plan/not all is lost. Will continue to hold
2 things required to get product ready for sale > demonstrate that you can write to the cell, and demonstrate how often you can write to the cell i.e. 10^17. Both of these will be demonstrated in the next platform round. Assuming success, the product will then be taken to potential acquirers. At the same time, they will likely start a 5th Platform lot to address any "functionality" that they haven't got data for but an acquirer might ask for.
You only get 1 shot with these people. 5 key players including Micron, Samsung, Hynix. They wont talk to you without a megabit array supported with extensive data. Fab would cost $5-$10bn to build so only large players would be interested. Ken Hurley will also then come back.
Likely 1 more raise in 2023 to fund platform 5. Another 12months of work
What went wrong: The cell is sufficiently complex that need circuitry to test if it works. Cannot see this visually, can only be seen by measuring the final product. Imec measures if its electrically active, which it was. The issue was it wouldn't move from a zero state to 1. Imec didn't think this was possible, very unusual error. But now have a new etch process, 2 other options as well. Testing them all thoroughly before starting the next platform lot
