Applications

To understand the potential benefits that Atomera’s unique material technology, MST®, can provide to consumers, we looked at how it could impact one of the most popular product in use today, the smartphone. As illustrated on the right, today’s smartphones are built with dozens of semiconductor devices, many of which could be improved with MST®. By replacing many of those devices with substitutes built using MST®, our analysis indicates that manufacturers could improve the phone’s battery life by up to 50 percent, enabling it to go more than two days between charges.

Our analysis also indicates that the cost to implement MST® on those devices will be offset by savings achieved through higher yield and chip size reductions enabled by MST®.

One drain on a smartphone’s battery life is mobile Dynamic Random Access Memory (DRAM), which consumes battery power continuously by refreshing the memory cells. The industry has moved through multiple generations of lower-power, better-performing mobile DRAM but those improvements have now slowed. We believe that MST® can be used to create a whole new class of mobile DRAM, allowing manufacturers to attain significantly faster access bandwidth while using a fraction of current power levels.

The smartphone is just one example of the breakthrough capabilities that MST is poised to deliver. The benefits of better-performing mobile DRAM alone can be extended to any battery-powered device, and may fuel creation of a host of new types of products for mobile and IoT applications. In addition, the power and cost savings delivered by MST® can help in network infrastructure, servers, automotive, and most other electronic products. By delivering a new way to squeeze more performance and power efficiency out of current manufacturing processes, MST solves today’s most challenging semiconductor manufacturing problems while opening the door to exciting new products and capabilities.

The smartphone offers a glimpse into MST’s exciting potential to revolutionize consumer electronics product design. Simulations show that, by replacing all of the phone’s devices with substitutes built using MST, manufacturers can improve the phone’s battery life by up to 52 percent, enabling it to go more than two days between charges.

Costs are also improved. The added expense of per-device MST license fees is more than made up by the savings from a 15 percent to 20 percent reduction in die size for each of the phone’s power management chips.

Additionally, MST solves the problem of the smartphone’s mobile dynamic random access memory (DRAM), which consumes battery power every few seconds to preserve information by periodically reading and rewriting it. The industry has moved through multiple generations of lower-power, better-performing mobile DRAM to versions using DDR4 memory, but cannot get to the next level of performance improvement offered by DDR5 memory without increasing power consumption. With MST, though, manufacturers can increase the performance of today’s DDR4-based mobile DRAMs, at significantly lower voltage than would be possible with DDR5 memory.

The smartphone is just one example of the breakthrough capabilities that MST is poised to deliver. The benefits of better-performing mobile DRAM, alone, can be extended to any battery-powered device, and will fuel creation of a host of new types of products for mobile and IoT applications. By delivering a new way to squeeze more performance and power efficiency out of current manufacturing processes, MST solves today’s most challenging semiconductor manufacturing problems while opening the door to exciting new products and capabilities.
