On the Sunday evening at IEDM last year, TechInsights held a reception in which Arabinda Das and Jeongdong Choe gave presentations that attracted a roomful of conference attendees. Arabinda was first up, giving a talk on the “10-year Journey of Apple’s iPhone and Innovations in Semiconductor Technology”, followed by Jeongdong discussing “Memory Process, Design and Architecture: Today and Tomorrow”.

Arabinda gave a broad-brush look back at the sequential development of the iPhone and its feature components – we tend to forget that the first one had no camera, fingerprint sensor, face recognition, etc., so it was definitely a trip down memory lane.

Jeongdong presented a review of the latest memory technologies seen by the reverse engineering specialists, summarising their recent analyses in a fair amount of detail, and which I’d like to go through in this article. Jeongdong is a Senior Technical Fellow at the company, and their subject-matter expert for memory technology. Before joining TechInsights, he worked as a Team Lead in R&D for SK Hynix and Samsung advancing next-generation memory devices, so he knows whereof he speaks.
