Comprehensive guarantees: Longsys DDR4 memory has passed KTI tests
2020.06.30
Following the launch of the full series DDR4 memories and the DDR4 modules based on CXMT's DRAM, Longsys has been exploring memory test technologies. In addition to introducing the independently developed test system based on 10nm ASIC, Longsys is also actively involved in cooperation with professional testing qualification institutions, in an effort to make breakthroughs in quality.
Last month, Longsys joined China Intelligent Hardware Evaluation Criterion Alliance (CIHEBA) formed by Ludashi, representing the recognition of Longsys’ testing technology by professional institutions.
Furthermore, Longsys and KingTiger Technology ("KTI”) have carried out a slew of exchange activities on memory technology and reached a strategic test framework agreement to improve memory test technologies and formulate relevant standards.
KTI, a world-renowned brand of memory test equipment, has specialized in the field of memory testing for over 30 years, and boasts complete core patented technologies. KTI operates under the philosophy of "equal emphasis on logic function testing and system application testing, and the application of industry standards and design specifications”.
With the support of China Aerospace Science and Technology Corporation, the project of aviation-grade DRAM test equipment R&D center and test service center has been launched. It is dedicated to memory device testing qualification and failure mode analysis, as well as mass-produced memory quality screening services. Through a joint mechanism with major manufacturers, it will be developed into an authoritative agency for memory testing.
Features of KTI test system
Recently, the FORESEE DDR4 UDIMM samples that Longsys provided passed KTI’s special test certification with the rating of "quality products”.

The testing has shown that memory product has exceptional performance in all terms of KTI's tests.
As a standard Longsys memory product, FORESEE DDR4 UDIMM is equipped with Samsung DRAM particles. It is produced by a world-leading company using high-end PCB process materials (30u gold plating process for edge connectors), guaranteeing its high quality for industrial users.
Specifications of FORESEE DDR4 UDIMM
Based on internal and external test systems, Longsys will continue to be committed to quality improvement and building a sound storage ecosystem in China.
Going forward, we will make diversified memory products available for KTI testing and certification and provide customers with more high-quality products!
