Next Steps – Demonstrate a megabit memory in a production-compatible process

• Develop a production-compatible process for the 4DS Interface Switching ReRAM technology in collaboration with imec using the same state-of-the-art process equipment currently in use by high-density high-volume memory makers.

• Demonstrate this production-compatible process with imec’s proven memory platform to build a 4DS megabit memory.

• Collect statistical significant data for yield, speed, endurance and retention at the megabit chip level that high-density high-volume memory makers & buyers need know to make informed decisions.
