China Xi'an UnilC Semi sells in-house DDR4 DRAM | AnandTech

[Martian2]

China has reached a milestone. Xi'an UnilC Semi is selling its own designs of DDR4 DRAM chips and modules.

"DDR4 SDRAM is the abbreviation for 'double data rate fourth generation synchronous dynamic random-access memory,' the latest variant of memory in computing. DDR4 is able to achieve higher speed and efficiency thanks to increased transfer rates and decreased voltage."

In simple English: DDR4 is the fastest computer memory available.

"DDR4 memory technology is up to twice as fast and delivers 50% more bandwidth and 40% more energy efficiency than DDR3 technology when it was introduced."

Chinese Xi'an UniIC Semiconductors Starts to Sell DDR4 Chips and Modules | AnandTech (February 24, 2018)

"Xi’an UniIC Semiconductors, a memory producer based in China, has started to sell DDR4 DRAM chips and modules that were developed and made in-house. This is the first time when a China-based company develops its own DDR4 memory chips.
...
Xi’an UniIC’s DDR4 lineup includes 4 GB and 8 GB SO-DIMMs, 4 GB and 8 GB UDIMMs as well as a 4 GB UDIMM with ECC, all rated for data transfer rate of 2133 MT/s with CL15 15-15 timings at 1.2 V (according to Xi’an UniIC’s DDR4 product decoder). All the DIMMs are based on Xi’an UniIC’s own DDR4 memory chips featuring 4 Gb capacity. The modules and the chips are not meant to offer breakthrough performance levels and are probably aimed at various inexpensive PCs, most of which will be sold in China."

"Lingjiu GP101“ GPU successfully taped out

中国人自己的显卡！国产3D GPU“凌久GP101”一次流片成功

2018年02月16日 11:41 转载：驱动之家 作者:驱动之家 分享

虽然在半导体领域相对世界顶尖水平差距很大，但中国也正在努力迎头赶上，国产CPU处理器、内存、闪存等等都在积极进取。现在，中国自己的显卡又要来了！

据新华社报道，由中国船舶重工集团公司第709研究所研发、具备完全自主知识产权的国产3D图形处理器芯片“凌久GP101”近日一次流片成功。

据介绍，凌久GP101 GPU芯片支持HDMI、DVI、VGA等通用显示接口，支持2D、3D图形加速和OpenGL ES 2.0，支持4K分辨率、视频解码和硬件图层处理等功能，可以广泛应用于军民两用电子设备、工业控制、电子信息等领域。

据悉，这是709所的GPU芯片研制中第三次一次流片成功，标志着国内自主研发GPU芯片已经具备批量生产能力，为后续相关研发和国产化应用打下了坚实基础。

背景介绍：

中国船舶重工集团公司第709研究所位于武汉东湖之滨，是武汉“中国光谷”的重要科研单位，是我国最早融计算技术、信息技术、自动控制、数学理论研究为一体的国家重点工程研究所，主要从事信息指挥系统、计算机加固技术、容错技术、并行处理技术以及网络技术与软件工程、图形图像处理、机电一体化、印制电路等专业的研究与开发工作。

709所以高新技术研究为中心，研制的系统和各类设备填补多项国内空白，为国防现代化和信息化作出了巨大贡献。

全所占地13.7万平方米，固定资产超亿元，科研实力雄厚，实验手段完善，仪器设备2000余台套，建有系统仿真、系统联调2个实验室，EDA、机械CAD 2个设计中心，集成电路测试、例行检测、软件测试4个检测中心，拥有设施齐全的电子装配、印制板制造和机械加工3条生产线。

709所现有职工千余人，其中国家级、省部级专家50余人次，研究员70余人，高级技术人员300余人。所内有独立的培训机构，负责全所职工的继续教育和研究生学历教育，现拥有3个硕士点，涵盖“计算机科学与技术”的全部二级学科，有一个博士点和一个博士后流动站，12个研究方向，20名研究生导师，其中博士生导师7人。

嗯，我们迟早也会有的

Whats the status of the chinese RAM products ? Is it some kind of pilot, limited production with sales only within the China ....

And most important, when chinese RAM is going to compete against Samsung, Hynix and Micron on the global market. Is it realistic to hope for large scale RAM chip production before 2020 ?
