1. Purple autonomous DDR4 memory exposure: a single 4GB;
Although our country in all areas of science and technology are by leaps and bounds, to meet or exceed the international top level, but the semiconductor field has always been a big short board, of course, we are also trying to catch up with the CPU processor, whether super or have a breakthrough in consumer areas, Memory storage is also a big step chasing.
Especially in the past two years, the sustained price of memory continued to soar. Samsung, SK Hynix and Micron firmly hold the power of discourse in the few oligarchs, which highlights the need for autonomy.
Now, Ziguang finally created China's first independent PC DDR4 memory chips, DRAM particles completely own research and development.
From the online exposure of the picture, this memory is clear purple core (UnilC) logo, is a simple bare design, a single capacity of 4GB, the more specific specifications do not see the parameters too clear.
Xi'an Ziguang Quoc Semiconductor Co., Ltd. was developed on the basis of restructuring and reconstruction of the original German Qimonda Technology (Xi'an) Co., Ltd. in May 2009 and was established in Xi'an as the Infineon Technologies Memory Business Unit in 2003. Infineon's storage division was split into the market for Qimonda, Qimonda Technology (Xi'an) Co., Ltd. was also established and began operating as an independent company.
In 2009, Inspur Group acquired the original German Qimonda Technology (Xi'an) Co., Ltd., and restructured it and renamed it Xi'an Hua Xin Semiconductor Co., Ltd. In 2015, Ziguang International Co., Ltd., a subsidiary of Ziguang Group, acquired Xian Wuxin Semiconductor Limited Company, and changed its name to Xi'an Ziguang Semiconductor Semiconductor Co., Ltd.
Xi'an Ziguang Guoxin core business is memory design and development, production and sales of private label memory products, as well as ASIC design and development services. At the same time also bear the national science and technology major projects' nuclear high base 'and the national high-tech development plan' 863 'And many other major areas of memory research projects and topics.
In January of this year, Ziguang Group announced that it will invest 200 billion yuan to build a semiconductor industrial base in Nanjing. Upon completion, Phase I will be the largest chip manufacturing plant in China, with a wafer production of 100,000 pieces per month.
In July last year, Purple also participated in the investment in the Yangtze River storage, which plans a total investment of 160 billion yuan to create a home-made 3D NAND flash memory, but also set up a 500-person R & D team to tackle DRAM memory manufacturing technology.
2. Taiyuan large into the Danzhou semiconductor industry into the fast lane;
December 22, 'Grand Courtyard entered Danzhou and semiconductor industrialization base unveiled' held in Pizhou City, Jiangsu Province, from Jiangsu Normal University, Jiangsu Institute of Industrial Technology, Nanjing University of Information Science and Technology, Peking University School of Microelectronics , Southeast University Scientific Research Institute, Chinese Academy of Sciences Institute of Microelectronics and many other domestic key universities or research structures of more than 200 experts and professors attended the meeting, Danzhou party secretary Chen Jing attended the meeting and delivered speeches.
Chen Jing, Party Secretary of Pizhou, and Wu Gang, Vice President of Southeast University, unveiled Wei Chaotang for Alliance of Technology Transfer Center of Dachang (Pizhou)
It is reported that in recent years, Zhuozhou main high-end semiconductor industry, adhere to the semiconductor materials and equipment industries as the explosive growth of emerging industries to promote the main thrust of innovation as the first to lead the development of power, adhere to the high-end industries 'siphon' high-end talent, Talent boost high-end industries.
At present, Pizhou gradually built the European semiconductor returnees Talent Pioneer Park, has nurtured the introduction of 'Thousand Talents Program' experts 35, foster the introduction of 'million people plan' experts 3, the introduction of the Nobel Prize winner 2, and the establishment of North Jiangsu first promise Bell Award winners studio. Established China Photolithography Technology Research Center, China Semiconductor Technology Innovation Center, Institute of Microelectronics Research Institute of Chinese Academy of Sciences Xuzhou Research Institute and other 'Guo Zihao' research platform, Pok Hong information, video speed photoelectric, the electronics, Huaxing laser And other leading type, base-type enterprises have settled down, the semiconductor electronic materials and equipment industry base successfully approved the national Torch industry base.

3. Super Battery R & D New Materials Battery Zhejiang 1.1 seconds full of electricity
Zhejiang University scientists used graphene membrane as the cathode material, developed a new type of aluminum - graphene battery. This battery life is extremely long, can be fully charged in a very short period of time, in the minus 40 ℃ to 120 ℃ temperature range Can work properly.This innovation pointed out an important direction for the practical use of aluminum ion batteries.
Al-ion battery is an excellent new battery, the key to practical use is to find a suitable cathode material.Zhejiang University Department of polymer superb professor of selected group of graphene amazing material, with innovative technology to prepare a unique graphene film as Cathode material, greatly enhance the overall performance of aluminum ion batteries, and now mainstream lithium batteries and super capacitors to contend with the prospect of very good.Related papers recently published in the international well-known periodical "scientific progress."
'The capacity of the battery, shown is its battery life.General battery with repeated charge and discharge, the capacity will continue to decline, which is what we say' not durable '.' Super said, 'aluminum - graphene battery at this point Then the performance is excellent.The battery has undergone 250,000 charge-discharge cycles, charging and discharging efficiency is still as high as 91%, capacity loss is very small. 'That is to say, if the smart phone with this battery, even if charging 10 times a day, Can be used for nearly 70 years.
This aluminum-graphene battery also offers superb rate performance with fast charging at high currents, while maintaining high specific capacitance. "Some smartphones also have fast charge capabilities, and it appears that the battery is quickly filled , The actual battery life is not long. 'Superb said that the new battery now laboratory data is 1.1 seconds will be fully charged, the loss of capacity than minor.' 'If you use the phone in the future, charging 5 seconds call 2 Hour is entirely possible. '
'Aluminum - graphene batteries in the rate performance, cycle life does not lose super capacitors, far exceeding the lithium battery in the energy density, although there is still a gap between lithium batteries, but significantly surpassed the super capacitor.' Super said the face of lithium batteries and Supercapacitors Both of these rivals, aluminum-graphene batteries have shown particular advantages, which can be called 'super batteries'.
Aluminum - graphene battery and some other current unmatched battery characteristics.Low temperature to minus 40 ℃, aluminum - graphene battery can still charge and discharge stability 1000 times, high temperature to 100 ℃, stable charge and discharge 45,000 times, even if the battery cell No exposure to fire nor fire or explosion This wide temperature range of use for the future of aluminum ion batteries in extreme temperature conditions laid the foundation for the use of this battery is also very flexible, after the bend capacity of 10,000 Fully retained, showing potential for use in wearable flexible electronic devices.
The superior performance of 'super batteries' stems from the excellent microstructure of the graphene film as a cathode material and the macroscopic efficiency it exhibits. Many of the important properties of a battery are excellent depending on how well electrons and ions can smoothly flow between positive and negative Very flow between the electrodes. Compared with other cathode materials, the advanced research group prepared graphene film, high-quality crystal lattice defects, highly oriented, with continuous tunnels, like a highway extending in all directions, allowing electrons and ions unimpeded.
