Longsys's FORESEE Launches UFS 3.1, a New-Generation Flagship High-Speed Flash Storage, Achieving a Leap Forward in Mobile Performance

2022.07.08


Storage products, especially mobile terminal storage products, have been evolving, driven by the introduction of 5G services. In the early days, mobile phone storage was in the form of an external SD card. It then evolved into embedded eMMC and eventually the more powerful UFS. The development of mobile phone flash memory has given rise to extensive intelligent applications that have improved the mobile phone user experience while speeding up data reading and writing.

Today, SD cards are gradually disappearing from mobile phones. Embedded storage products have taken the lead in the mobile terminal storage market. Most early smartphone flash memory used the eMMC standard. However, eMMC 5.1 cannot fully support the massive data throughput of 5G and struggles to meet the performance requirements of the latest mobile applications. As a result, many intelligent mobile terminals are now using UFS chips.

Since JEDEC released the new UFS 3.1 standard in 2020, Longsys's embedded storage team has been committed to R&D and testing. After two years, Longsys successfully launched the FORESEE UFS 3.1 protocol, which is currently being tested and validated.

 

Enhanced mobile performance makes transferring easy

As FORESEE's new-generation flagship embedded storage, UFS 3.1 boasts significantly optimized performance and reduced transfer latency. It offers write speeds up to 1,200MB/s, which is nearly three times faster than the previous UFS. It significantly improves the efficiency of mobile devices. In addition, UFS 3.1 can meet functional requirements such as instant boot, fast boot, and multi-tasking. It can also reduce application loading time to facilitate 5G mobile device acceleration.

A smooth path to 5G connectivity

FORESEE's UFS 3.1 is currently available in 128GB, 256GB, and 512GB capacity options to meet mainstream market demand. The product is designed to be as thin as 1.0mm to be flexibly compatible with the internal space of mobile terminals. The product is widely used in flagship smartphones, tablets, AR/VR devices, high-speed smart cameras, intelligent vehicles, and 5G IoT devices.

Additional multiple features provide a new experience

With our strong team of engineers, Longsys has independently developed firmware features such as Write Booster, low power management, thermal throttling, and Host Performance Booster in accordance with the UFS 3.1 standard released by JEDEC. These features ensure that flash memory chips deliver superior performance to keep mobile devices running at a constant temperature with low power consumption. These features allow mobile devices to achieve an optimal performance-to-power ratio and increased battery life.

·       Write Booster

The Write Booster feature significantly improves the burst write performance of devices using FORESEE's UFS 3.1. This improvement is made possible by the internal cache storage of UFS 3.1. The cache storage receives files at high speed and continues to do so until the flash memory's bandwidth becomes available. The written files are then transferred from the cache to the regular flash memory.

·       Low Power Management

FORESEE UFS 3.1 has excellent low power management. It enables terminal devices to quickly enter and exit the low-power mode to ensure that devices operate at low power without compromising the user experience.

·       Thermal Throttling

When the internal temperature of a mobile device using FORESEE UFS 3.1 becomes too high, the device will automatically activate the thermal threshold feature to avoid abnormalities or loss of user data due to high temperature. In addition, when the device overheats, FORESEE UFS 3.1 will also command the system to limit read and write performance, thus reducing flash memory temperature.

·       Host Performance Booster

The HPB feature can be used to enhance the read performance of devices using FORESEE UFS 3.1. The principle is to utilize the phone's RAM to relieve the pressure on flash memory to improve read performance.

Outlook

With the popularization of technologies such as 5G and AI, the share of UFS products in the mobile terminal application market has been expanding rapidly. UFS 2.2/3.1 protocols are now more mature and competitive in performance and technology than earlier UFS standards. We can expect more and more mainstream mobile terminals to use UFS chips.

 

The widespread adoption of UFS chips heralds performance iterations in IoT, intelligent vehicles, and other areas. Longsys will launch a range of automotive FORESEE UFS products this year to help industry customers seize market opportunities.
