I still remember the rumors of the domestically produced DDR4 chips that had been raging in the past. At that time, it was reported that Ziguang’s semiconductor company produced the first DDR4 memory in China, but this was a bit of a doubt. Finally, Ziguang officially nicknamed that there is no DDR4 memory. Mass production, related products are under development. Let's take a look at the related content with the network communication Xiaobian.
Domestic memory is really coming: Violet can provide DDR3, DDR4 memory chips
Nowadays, domestic DDR4 memory has come again, involving Xi'an Guoxin Semiconductor, which is owned by Ziguang. Its official website clearly mentions DRAM chips and bare wafers that can supply DDR3 and DDR4 for a long time.
This time, the domestic DDR4 is also a subsidiary of Ziguang Group, Ziguang Guoxin, which owns Xi'an Ziguang Guoxin, Shenzhen Guowei, Ziguang Tongchuang and other companies. According to the official website, "Ziguang Guoxin is a listed company in the semiconductor industry of Ziguang Group, focusing on the design and development of integrated circuit chips. It adheres to stable operation, continuous innovation and open cooperation. It is currently the leading integrated circuit chip design and system integration solution in China. Suppliers." Their DRAM memory technology comes from the acquisition of Qimonda Xi'an, so it has DDR memory technology research and development, production capacity.
Domestic memory is really coming: Violet can provide DDR3, DDR4 memory chips
The previously rumored domestic DDR4 memory is actually the DDR3 memory of Xi'an Guoxin. Ziguang also said that DDR4 memory has not yet been mass-produced and is still under development. However, the official website of Xi'an Guoxin mentioned that it can supply various DDR for a long time. Memory, including SDR, DDR2, DDR3, and DDR4 memory, means they can now produce DDR4 memory chips and modules.
But the problem is, click this page, they provide DDR memory specifications only DDR3, can provide a minimum core capacity of 512Mb, the highest 4Gb DDR3 chip, the voltage is 1.35-1.5V, the frequency is not high, the lowest 1066MHz, the highest Also 1866MHz.
The above is about network communication - domestic memory is really coming: Ziguang can provide DDR3, DDR4 memory chip related introduction, if you want to know more information, please pay attention to eeworld, eeworld electronic engineering will provide you with more complete, More detailed and updated information.
