At its annual Memory Tach Day in October, Samsung showcased several new memory products and industry-first innovations for future applications. Among those was its LLW (Low Latency Wide IO) DRAM specialized for on-device AI. The new solution is expected to arrive next year. While the official launch is still a few months away, more information about the special type of DRAM has now surfaced online.

Samsung’s LLW DRAM is substantially more power-efficient

According to Samsung, LLW DRAM increases bandwidth and latency limits, making it significantly more efficient than standard LPDDR DRAM. The company is touting a massive 70 percent boost in power efficiency, while simultaneously increasing the processing speed. The advanced solution achieves this by increasing the number of input/output (I/O) terminals in a semiconductor circuit.

The next-gen DRAM solutions can quickly and efficiently process large amounts of real-time data, making it ideal for mobile AI and gaming applications. A teaser video posted on X by Samsung shows its applications across a wide range of products, including smartphones, laptops, XR (extended reality) headsets, and gaming consoles. On smartphones, LLW DRAM may be stacked directly above the application processor (AP).

Considering the rumored launch timeline, Samsung may equip its upcoming XR headset with LLW DRAM. Apple has already implemented the tech in its R1 chip powering the Vision Pro XR headset. The Korean firm is expected to bring its rival to the market next year. It would want to match or even better the competition in all areas, from the technological strength to content and features.

Apple’s R1 chip also employs the Fan-Out Wafer-Level Packaging (FOWLP) technology (via Revegnus). Samsung is packing the Exynos 2400 using this tech. Its AP for the XR headset may feature the FOWLP packaging tech too. We should come across more information about Samsung’s LLW DRAM solutions and the XR chipset in the coming months.

Samsung’s XR headset will be available in limited quantity next year

According to reports, Samsung will debut its XR headset in the second half of 2024. The product, which the company co-developed with Qualcomm and Google, may go official during the Galaxy Z Fold 6 and Galaxy Z Flip 6 launch in July or August next year. However, sales won’t begin until very late in the year. Moreover, the firm will release the device in limited quantity initially. Reports have hinted at a first production volume of just 30,000 units. It may expand production later depending on the market demand for the device.
