Alongside the top position in smartphone sales, Samsung is also known as a leader in advanced memory technology, which has recently unveiled the industry’s first 512GB DDR5 module based on High-K Metal Gate (HKMG) process technology.

Compared to DDR4, the DDR5 delivers more than 2x performance that makes it capable of orchestrating the most extreme compute-hungry, high-bandwidth workloads in supercomputing, artificial intelligence (AI), and machine learning (ML), as well as data analytics applications.

According to Samsung, the DDR5 will utilize highly advanced HKMG technology that has been traditionally used in logic semiconductors. After continuous scaling down of DRAM structures, the company has finally thinned the insulation layer, which leads to a higher leakage current.

By replacing insulators with HKMG materials, Samsung’s DDR5 will be able to reduce leakage and reach a new level of performance. This new memory will also reduce power consumption by approximately 13%, making it particularly suitable for data centers where energy efficiency is increasingly important.

The HKMG process was first adopted in Samsung’s GDDR6 memory in 2018. By expanding the use of DDR5, Samsung has further consolidated its leading position in next-generation DRAM technology.

Samsung DDR5 uses TSV technology to stack eight layers of 16Gb DRAM chips to provide a maximum capacity of 512GB. TSV was first used in DRAM in 2014 when the company introduced a server module with a capacity of up to 256GB.

The Korean tech giant is currently providing customers with different variants of its DDR5 memory product line for verification and finally certification through its leading products to accelerate AI/ML, exascale calculations, analysis, network, and another data-intensive Workload.

Samsung Galaxy S25 Ultra can boost camera features with variable aperture, if it actually happens

Published

on

Samsung Galaxy S24 Ultra

Samsung has a tonne of upgrades for the Galaxy S25 Ultra including a high pixel sensor and better videography capabilities but the flagship could get even more interesting if it equips a variable aperture camera system.

Samsung uses high-quality main lenses with the S series including the latest 200Mp module. The company has utilized this lens for Galaxy S23 Ultra and S24 Ultra, and it will likely come with Galaxy S25 Ultra.

Instead of the exact same module, the Galaxy S25 Ultra will get some photography and videography upgrades via new algorithms. Besides, you can have new camera app experiences thanks to the One UI 7.

So, it would be a mixed camera upgrade for the main lens. However, you can anticipate improvements in telephoto or ultra-wide angle to get some new improvements.

But what if Samsung adds a variable aperture to this new flagship device? That would be a key highlight for all photography enthusiasts.

Variable aperture enables you to change the aperture size by controlling the amount of light entering the camera.

In the background, the mechanism uses physical hardware that collaborates and changes the apertures using blades with opening and closing sequences.

It offers numerous advantages over a fixed aperture camera including:

  • Low-light control – A large aperture can enter more light into the sensor to brighten the scene and reduce noise in low-light conditions.
  • Depth Control – The aperture also controls depth of field, a large aperture creates a shallow depth to isolate a subject from the background. On the other hand, a smaller aperture creates a depth of field for landscape photography.

Galaxy S9 – The start and evolution

Variable aperture is not new to the smartphone industry, in fact, it has been available for years. Interestingly, Samsung was the first to popularize variable aperture with the Galaxy S9 in 2018.

The Galaxy S9 and S9+ feature dual aperture, which automatically adjusts and passes light to the sensor. It can switch between F1.5 and F2.5 for dark and light photography environments respectively.

Unfortunately, the Korean tech giant dropped this tech with the Galaxy S10 and went back to fixed aperture. So, Samsung is familiar with this tech but it will require some new advancement step ahead in the competition.

Chinese phone makers including Huawei and Xiaomi have led this tech to a new level in recent flagship devices. A more sophisticated multi-blade aperture system has evolved including the 6-blade architecture.

This offers better light control, quality, and depth of field than ever before. These and other smartphone companies are searching for new variable architecture to improve the overall design and quickness of closing and opening the blades.

Even some reports suggest that Apple could also adopt variable aperture for its upcoming iPhone 17 in 2025.

Why it should

Compared to its competitors, Samsung uses the top-of-the-line 200mp camera system and due to the sheer pixel density, It can experiment with these aperture sizes to bring the best for consumers.

Note: Samsung has not confirmed the variable aperture camera for the Galaxy S25 Ultra. So, we can only remain optimistic about the photography enhancements with this upcoming flagship.

Galaxy S26 Ultra?

If it doesn’t happen with the Galaxy S25 Ultra, we’ll have to wait for Samsung’s next S-series flagship – S26 Ultra in 2026. Yet, things remained unconfirmed from this point of view.

Samsung Galaxy S24 FE

Samsung may not release the Galaxy S25 Slim early next year. The company could stick to its usual launch strategy of introducing new Galaxy S flagships. The additional Slim-branded variant could come out a few months later.

According to MaxJambor, the Samsung Galaxy S25 Slim won’t release alongside the Galaxy S25 lineup. The source confirmed that the S25 Slim “exists behind closed doors,” suggesting that the phone is still under consideration.

Apart from this, Max also claimed that the Galaxy S25 Slim won’t replace the Galaxy S25 FE. That said, pro-grade hardware specifications are highly likely on Samsung’s rumored Slim-branded flagship smartphone.

The Samsung Galaxy S25 Slim exists behind closed doors, but if it’s set to launch at some point, it won’t be released alongside the rest of the S25 lineup.

IceUniverse recently revealed that the Galaxy S25 Slim could pack an “Ultra” camera. The cryptic X post hints at a 200-megapixel sensor on the S25 Slim. However, the other camera specifications remain yet to be known.

Recently, Samsung’s SM-S937U was spotted on the GSMA IMEI database. The model number hints at a fourth Galaxy S25 variant that could be Slim or Special Edition. The phone is said to feature a thinner design than the other S25 flagships.

Samsung is considering bringing the Galaxy S25 Slim to compete with Apple’s iPhone 17 Air. It is reported that Apple has finalized the iPhone 17 Air with a slimmer design and single camera, but it could replace the iPhone 17 Plus.

The South Korean tech giant might drop the first hint at the Galaxy S26 design with the Galaxy S25 Slim. Korean media reported that the S25 Slim’s market response will decide how Samsung will design the Galaxy S26 series to be released in 2026.
