This week, at the 2024 IEEE International Electron Devices Meeting (IEDM), imec, a world-leading research and innovation hub in nanoelectronics and digital technologies, proposes a novel 3D integrated charge-coupled device (CCD) that can operate as a block-addressable buffer memory, in support of data-intensive compute applications. Memory operation is demonstrated on a planar proof-of-concept CCD structure which can store 142 bits. Implementing an oxide semiconductor channel material (such as IGZO) ensures sufficiently long retention time and enables 3D integration in a cost-efficient, 3D NAND-like architecture. Imec expects the 3D CCD memory density to scale far beyond the DRAM limit.

The recent introduction of the compute express link (CXL) memory interface provides opportunities for new memories to complement DRAM in data-intensive compute applications like AI and ML. One example is the CXL type-3 buffer memory, envisioned as an off-chip pool of memories that 'feeds' the various processor cores with large data blocks via a high-bandwidth CXL switch. This class of memories meets different specifications than byte-addressable DRAM, which increasingly struggles to maintain the cost-per-bit-trend scaling line.

CL CSOT, a company focused on developing new technologies and innovations in the display industry, today unveiled over 30 of its latest products and advanced technologies, including more than ten firsts in the world, at Display Week 2023 organized by the Society for Information Display (SID), held from May 21 to 26 in Los Angeles, California.

Guided by the vision of "Display A Better Future For All", TCL CSOT showcases its expertise and capacity in providing complete display technology solutions across a range of sizes, categories, and forms - spanning IJP OLED, Mini LED, Micro LED, medical displays, vehicle-mounted displays, light field displays, as well as consumer electronics displays. Among them, six core exhibits include:

IGZO or Indium Gallium Zinc Oxide is a type of semiconducting material that has been used in displays by Sharp since 2012, although mainly for mobile devices courtesy of being more power efficient compared to standard IPS panels. There doesn't seem to have been much interest by other players in the display industry to use the material, although there have been other IGZO based display panels in the past. However, at Touch Taiwan, InnoLux showed off no less than two new display panels relying on IGZO, both targeting gamers. Both panels measure 27-inches and support HDR 600. The 2560 x 1440 model is capable of a massive 480 Hz, a refresh rate that was only possible using TN panels to date.

The second display panel offers 3840 x 2160 resolution at 240 Hz, which isn't unique on the market, but as these IGZO panels are based around IPS rather than VA technology, they shouldn't suffer from the dreaded ghosting that many VA panels suffer from. InnoLux was very sparse on other technology details, but both panels have a 98 percent DCI-P3 colour gamut coverage and the QHD display has a grey to grey response time of 3 ms, whereas the 4K variant is a bit higher at 5 ms. Both panels looked stunning and this might be what many gamers have been waiting for, at least as a stop gap before OLED displays become more affordable.
