ICTECH 2018 The China storage chip independent research and development technology exchange summit is hosted by Nantong national high tech Zone and Jiangsu Huacun Electronic Technology Co., Ltd ,IC Coffee contractor . This symposium aims to discuss the current situation and development of integrated circuit localization , The technical bottleneck and breakthrough of independent research and development of memory chips , And the future prospects for the safety and reliability of the storage industry made in China .

Mr. Jianghong, deputy director of the Department of science and technology of Jiangsu Province 、 Member of the Standing Committee of Tongzhou District Committee of Nantong City , Mr. zhangxingguo, deputy secretary of the Party Working Committee of Nantong high tech Zone, made a wonderful speech for this Conference . Huirong technology SMI Senior vice president Duan Xiting 、 Jingyuan Electronic Group CEO Liu anxiuan 、 Xue Jialin, President of qingkong asset management group 、 smic SMIC Senior business director Hu Zhaolin 、 Wang Yanhui, Secretary General of China Mobile Alliance, and other industry celebrities , At the meeting, we independently researched and developed memory chips 、 market trends 、 Industrial Development and so on . Wei Zhifan, general manager of Jiangsu Huacun's master design division, and Zhuang Jianmin, deputy general manager of the scheme verification and design office, addressed the guests 、 Leaders and partners independently design memory chips 、 In depth analysis of memory scheme design verification and challenges .

“ We see the rapid development of artificial intelligence, the Internet of things and the Internet in the Chinese market , face 5G Times are coming , Data increases rapidly , Storage demand has also increased rapidly .” Huirong technology SMI Senior vice president Duan Xiting said . He thinks that , The growth point of storage applications has shifted from smartphones 、 Consumer electronics such as tablet computers have expanded to the Internet 、 Artificial intelligence 、 Cloud computing 、 Security field , The technical requirements are becoming more and more stringent . At the same time, he believes that with the development of flash memory technology in China , As the world's leading flash memory master manufacturer, we also look forward to China's memory core industry manufacturers to quickly integrate with the world .

The listing of a chip is inseparable from the upstream and downstream design of the semiconductor industry 、 manufacture 、 encapsulation 、 Close cooperation between testing and other industries . Jingyuan electronic group, a professional testing company, attended the meeting as a close partner of Huacun , Jingyuan Electronic Group CEO Liu anxiuan said ,eMMC The master control of high-order storage is blank in China , Huacun has made great contributions to this . Jingyuan electronics has always cooperated closely with Huacun , Overcome difficulties together .

Xue Jialin, President of qingkong asset management group, believes , Whether it's DRAM, still NAND Flash, All belong to bulk commodities in the field of integrated circuits , The industry's demand for memory is stable , Although the whole semiconductor industry has entered a downward cycle , The growth of memory is no slower than that in previous years , However, the demand for import substitution of memory master chips is still very strong . He said ：“ After years of accumulation in this field, Huacun Electronics , Ready to go , Strive to win an advantageous competitive position in the market .”

At the meeting, Wei Zhifan, general manager of the main control design business department of Huacun, gave a keynote speech with the theme of independent design of memory chips , In addition to introducing the current situation of domestic integrated circuits and memory chips , It also expounds how enterprises move towards independent research and development and the importance of independent research and development capability to the storage industry . He shared Huacun's choice to eMMC As a starting point , How to develop domestically made eMMC Memory master chip , And extend to its corporate vision and mission .

smic SMIC Senior business director Hu Zhaolin said ,SMIC At present, it is the largest chip manufacturing leader in China , Facing the new opportunities created by the new era in the future , SMIC How to use it in important applications for future growth , Carry out strategic alliance and platform layout in advance , With continuous technological innovation , To fully support the domestic chip design industry , Jointly grasp the opportunities of the Greater China market , March towards the future together .

There are also many challenges in flash chip design and scheme verification . Zhuang Jianmin, deputy general manager of Huacun scheme verification and design office, said , Today's demand for mass storage products , It has changed from traditional disk storage and removal device to flash storage and removal device , It is not just a simple capacity demand, but also to consider the transmission speed and stability of the product , The transmission interface changes from low-speed parallel transmission to high-speed serial analog transmission , Flash memory speed is also a multiple increase , At the same time, it should have the performance of low power consumption and high stability , At this time, the scheme design is more difficult , The master control design and its related scheme design verification need to be matched more perfectly .

The vigorous development of independent research and development chips , Quickly connect with the world . It is inseparable from the favorable conditions such as national policies and industrial foundation , Of course, we should also firmly grasp China IC Opportunities for industrial development . Wangyanhui, Secretary General of the China Mobile Alliance, believes , China is the world's largest manufacturing base , Compared with other countries , China has given IC start-ups more opportunities , This is also China's integrated circuit, especially IC The basis for the development and expansion of the design industry , I hope the industry can seize this wave of industrial upgrading opportunities .

chart | Jiangsu Huacun master chip HC5001 Application plan

The master chip released by Jiangsu Huacun HC5001 Both high compatibility and high stability , Support for 5.1 Version embedded memory standard (eMMC5.1)、 Support three-dimensional structure flash memory materials (3D TLC NAND Flash)、 Support random read write flash memory high stability performance algorithm （FTL）、 Support high-speed flash memory interface （ONFI3.2/ToggIe2.0）、 Support high reliability low density parity check code error correction algorithm (LDPC), as well as 40nm The process meets the level of high efficiency and low power consumption eMMC Embedded storage device requirements .

With the continuous improvement of the nano microfabrication process , Storage products need to keep erasing life longer , The probability of error becomes lower , Read and write faster , The strong performance of compatible memory control chips is indispensable for the stability enhancement . In recent years , Portable electronic equipment 、 The wave of portability swept the market , The tablet 、 A smart phone 、 Smart TV 、 Wearable device 、 robot 、AR/VR、 The demand of emerging application markets such as electric vehicles is in the global upsurge , Embedded storage eMMC Device hard disk came into being , This also puts forward higher requirements for storage devices , Like multimedia playback 、 High definition video 、GPS, Various applications and the development trend of light and compact appearance . The storage device is required to have high capacity 、 High stability and high reading and writing speed at the same time , The storage device must occupy less space in the motherboard . from 2014 Embedded storage eMMC Device hard disk number 5.1 Since the release of version specification ,eMMC Device hard disk in 2017 In, it has occupied the consumer mobile storage market for more than 90% The scale of , All are monopolized by manufacturers in the United States, Japan and South Korea , Jiangsu Huacun has successfully achieved a breakthrough of zero localization rate , In a real sense, it realizes the domestic made embedded storage , It has set a milestone for mobile storage China core .
