I still remember the buzz surrounding domestically produced DDR4 memory chips a few years ago. At that time, there were reports claiming that Ziguang Semiconductor had developed China's first DDR4 memory. However, this caused some skepticism. Eventually, Ziguang officially clarified that they had no plans for mass production of DDR4 memory, and it was still in the development stage. Let’s take a closer look at what’s really going on with the domestic memory industry.

Nowadays, there are new developments in the domestic DDR4 memory market. The company involved is Xi'an Guoxin Semiconductor, which is part of the Ziguang Group. According to their official website, they have been supplying DDR3 and DDR4 DRAM chips for a long time. This time, the DDR4 memory comes from Ziguang Guoxin, a subsidiary of Ziguang Group. It includes companies such as Xi'an Ziguang Guoxin, Shenzhen Guowei, and Ziguang Tongchuang.
According to the official description, "Ziguang Guoxin is a listed company in the semiconductor industry under Ziguang Group. It focuses on the design and development of integrated circuit chips, adhering to stable operations, continuous innovation, and open cooperation. It is currently one of the leading suppliers of integrated circuit chip design and system integration solutions in China."
Their DRAM technology was acquired from Qimonda Xi'an, which gave them the capability to develop and produce DDR memory. This means they now have the technical foundation to support DDR4 memory production.

However, the previously rumored DDR4 memory was actually DDR3 from Xi'an Guoxin. Ziguang has confirmed that DDR4 is not yet in mass production and is still under development. Despite this, the official website of Xi'an Guoxin states that they can supply various types of DDR memory, including SDR, DDR2, DDR3, and even DDR4. This suggests that they may already be capable of producing DDR4 memory chips and modules.
But there's a catch. When you visit their product page, the only DDR memory specifications available are for DDR3. They offer chips with a minimum capacity of 512Mb and a maximum of 4Gb. The voltage ranges from 1.35V to 1.5V, and the frequency is relatively low—starting at 1066MHz and going up to 1866MHz.
This raises questions about whether they are truly producing DDR4 or just rebranding DDR3. Regardless, the fact that a domestic company is actively working on DDR4 is a significant step forward in China's semiconductor industry.
