Q1 2019 Target, page-340

rough numbers: $4 million cash available.
Assume current burn rate of $1m per quarter continues until September and 1mb chip is produced. 
leaves 4DS with ~$1m left to pay for marketing, admin and board fees. which would last say 6 months? is that enough time to close a deal?

i think they will try raise at least $2m in the third quarter again.

This assumes there is no take over or agreement with a NRE payment made before then.

worst case they keep development going after 1mb chip, to scale down to 28nm or below and try raise $4m plus.
