The global memory market is dominated by three companies, Samsung, SK Hynix and Micron. The combined value of the three companies is as high as 95%. It is not easy for China to break through the blockade in the memory market. Despite Ziguang, Changxin, Zhaoyi Innovation, etc. Invest in the memory chip market, but in the existing DDR memory technology, Chinese company technology, production capacity is still far from it.
In addition, the memory is not limited to traditional DDR technology. There are many emerging areas being developed, such as PCM phase-change memory, which has many advantages over traditional memory, such as 1000 times faster and 1000 times more durable than conventional memory. The Huai'an City Time Core Deposit Company invested 13 billion yuan to build China's largest phase change storage base. It has officially started operations last week and is expected to have an annual output value of 4.5 billion yuan.
According to news from Jiangsu, China, the launch of the integrated circuit industry in Huai'an City on March 22 and the launch of phase-change memory factory completion of Jiangsu Times Semiconductor Co., Ltd. were successfully held in Huai'an High-tech Industrial Development Zone, marking 130 The phase-change storage project invested by 100 million yuan began to enter the operational phase. This project completed the capping of the plant in November last year, and completed the procurement of equipment. It took less than 9 months from start of construction to capping, and it began operation at the end of March this year.
According to previous news, the Huai'an project in Jiangsu Province has a total investment of 13 billion yuan. The first phase will invest 4.3 billion yuan. After the completion of the project, it will annually produce 100,000 12-inch PCM phase-change memory chips. Phase-change memory chips have become the 21st century memory chips. Standard, compared with traditional memory chips (such as memory), it is a non-volatile memory chip, but the speed is up to 1000 times that of traditional memory chips, while the reliability is 1000 times the latter - of course, these indicators are It is theoretical.
The current mass production of PCM memory chips is not so strong. Intel's 3D XPoint flash memory is said to be a PCM memory chip, but it has not been confirmed. Its advertised feature is that the performance is 1000 times that of flash memory. The reliability is also flash memory. 1000 times, while the capacity density is 10 times that of flash memory.
