4DS Memory Limited provided an update regarding a testing capability upgrade and management changes. 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 the company's 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.
