ASX RELEASE

10 February 2022

TESTING CAPABILITY UPGRADE AND MANAGEMENT CHANGES

4DS Memory Limited (ASX:4DS) ( 4DS ) (the Company ), today provides an update regarding a testing capability upgrade and management changes.

Third Platform Lot Testing Capability

With the reported transition from Non-Platform Lot wafers to the Third Platform Lot wafers with one megabit memory arrays of memory cells with access transistors, the Company has reviewed its test options and identified the need to replace its home-built low-cost test capabilities.

The Company has decided to adopt a new test system based on commercially available components to test the Third Platform Lot wafers estimated to come out of the fab in July 2022.

Chief Engineering Officer

Now that the Company has decided to adopt a commercial test system, the role of the Company’s Chief Engineering Officer, having been the architect of our home-built testing system, will be significantly reduced. As a result, effective February 1, 2022, Mr. Mike van Buskirk, has switched to a part time role and will retire at the end of October 2022 after he has aided the Company in successfully bringing up this new test capability.

Chairman Wilbert van den Hoek commented “Mike has been instrumental in the development of 4DS’ Interface Switching ReRAM and will continue to play an important role as we look towards the testing of the Third Platform Lot later this year. The redefining of his role is also a significant cost saving to the Company and will partially offset the expenses associated with setting up a commercial test system in-house”.

Chief Executive Officer and Managing Director

Taking responsibility for the disappointing results in 2021 and acknowledging the need to preserve the Company’s cash, Dr Arnout has volunteered to cut his salary by 50% until the Company has successfully demonstrated a megabit memory array.

ENDS
