With the rapid development of advanced technologies, such as 5G, the Internet of Things (IoT), Artificial Intelligence (AI), and 8K, people are placing more stringent requirements on the convenience, intelligence, and functional integration of their electronics.
Longsys recently launched the FORESEE DDR4, which utilizes 96ball thin fine ball grid array (TFBGA) encapsulation. The product's manufacturing process, transmission speed, power consumption, and high-temperature reliability all perform at an industry-leading level.
Based on a 10nm application-specific integrated circuit (ASIC) chip test solution, Longsys has applied its innovations and customizations to the LS428, to provide high-speed, high-frequency, large-scale, and low-power automatic test equipment (ATE) and support the development of test programs. LS428 can test a maximum of 4800 DDR4 products simultaneously for speed (up to 1600 MHz), function, and high-temperature aging. In addition, with its expertise in innovation, Longsys has developed a test socket that can perform direct high-temperature testing by enabling a linear temperature rise from 0°C to 125°C. This avoids the hassle of having to remove the chip from the bench and send it to a high-temperature box for testing, as is required in conventional high-temperature testing.
For storage products, the unique feature of memory particles plays a vital role in a product's performance. As many memory particles featuring different types of manufacturing/processes, capacities, and grades of quality exist on the market, it is difficult for industry customers to select a suitable one. Longsys has created a customized and stringent particle admission process and uses pressure tests which are higher than industry requirements to ensure product stability and reliability.

In addition to the common Integrated Product Development (IPD) process, Longsys adopts a technical review and decision-making review. This ensures neutral decision making and an independent technical review process. Through earlier evaluation of product stakeholders' requirements, the company aims to meet customer requirements and increase customer value.
As a part of quality management, the production test plays a key role in ensuring product reliability. Longsys Zhongshan Storage Industrial Park, equipped with professional laboratories and various experimental equipment, was completed and put into operation in 2019. Longsys products are tested based on in-house test cases, providing a reliable test environment. Each FORESEE DDR4 product has undergone over 40 test items related to high temperature aging, high temperature pressure, and performance testing. These tests guarantee the delivery of highly reliable products to industry customers.
The FORESEE DDR4 employs the most advanced 1α nm process. Compared with a traditional 1x nm process, the 1α nm process further improves the product's performance with manageable costs. In addition, the product has a high-speed clock frequency that ensures an efficient read and write performance of 3200Mbps and provides high-speed caching for real-time updating of applications.
The DDR4 mainly applies to devices with a thin and compact structure. In limited spaces, heat dissipation efficiency can become its shortcoming. Under high temperatures, the product enables automatic temperature refresh, and its built-in temperature sensor improves the frequency of automatic refresh, so as to ensure accurate data.
With consumers exhibiting more diversified and high-end consumption behavior, 8K smart TVs, network-attached storage (NAS), portable wearables, and other terminals will become increasingly mainstream in the market. To meet the storage requirements of this burgeoning field, FORESEE will further develop this segment of storage products to promote the growth of smart and small-sized electronics.
