ASX RELEASE

29 November 2023

Company update and 2024 imec contract extension

4DS Memory Limited (ASX:4DS) ( 4DS ) (the Company ), is pleased to provide a summary of the 2023 Company technology achievements, the imec 2024 contract extension and the appointment of a strategic advisor.

Company Technology Achievements for 2023

On 23 August 2023, the Company announced that, as a consequence of all the development activities which had taken place since 5 October 2022, it had now demonstrated the successful transfer of all new process improvements and learning cycles developed at the Stanford Nanofabrication Facility into imec’s megabit array.

These process improvements included modification of the PCMO etch process and the composition of the memory cells, and it validated that the technology optimization was transferable from fab to fab.

After extensive analysis 4DS showed, for the first time, a fully functioning megabit array with 60nm memory cells, access transistors and write circuitry.

On 18 September 2023, the Company informed shareholders that it had successfully completed further analysis of the Fourth Platform Lot and the results obtained were significantly better as compared to results announced on 23 August 2023.

The Company confirmed that following additional testing within the megabit array 4DS had shown:

• Write speeds at 9.5 nanoseconds which were significantly superior to DRAM;

• Endurance in excess of 3 billion cycles;

• DRAM read speed; and

• Retention is persistent and tuneable.

4DS’ ReRAM performance profile to suitably meet these outcomes had again been clearly demonstrated on the Fourth Platform Lot via the additional testing.

imec 2024 Collaboration Agreement

Following lengthy strategic discussions, 4DS and imec have today finalised the terms of the collaboration extension which will now commence on 1 January 2024 and run to end of the same year.

4DS and imec have agreed to additional collaboration activities to be undertaken during 2024. The consideration for all collaboration activities is 1.92 million Euro.

imec manufacture of Fifth and Sixth Platform Lots

Process optimization and short loop analysis will take place over the balance of 2023 and into early 2024.

The Fifth and Sixth Platform Lots will again be manufactured on imec’s unique Dory platform on 60nm and significantly for the first time 20nm memory cells.

Manufacturing of the Fifth and Sixth Platform Lots will commence during Q1 2024 and Q2 2024 respectively with delivery to 4DS expected during Q3 2024.

The Fifth Platform Lot is seeking to further optimise the unique characteristics of the results already seen on the 60nm memory cells prior to undertaking manufacturing of the Sixth Platform Lot on 20nm memory cells.

4DS’ Executive Chairman, Mr David McAuliffe stated “Today’s ever-growing computing landscape presents a growing challenge to solve for platforms, applications and system designers, with massive shifts taking place, including the rise of Generative AI, and other related advances, resulting in severe processing bottlenecks.

“With a strong balance sheet and a much-reduced dependency on raising additional capital, unless it was a strategic placement, the Board is of the view that this increased investment at imec is in the best interests of shareholders to potentially maximise the opportunity to further position 4DS as a unique technology to address gaps in the market.”

Further, Mr David McAuliffe stated, “In light of this significant investment and the potential outcomes in 2024, we are delighted to announce the appointment of Mr Peter Himes as a strategic advisor to the Board.”
