Remember some time ago hubbub of domestic DDR4 chip rumors? At that time there was news that the semiconductor company under the purple light mass production of the first DDR4 memory, but this is a matter of doubt, and finally Purple official also rumor that there is no DDR4 memory Production, related products are being developed.
Now domestic DDR4 memory again, involving the state of Xi'an or under the core of the semiconductor, the official website page clearly mentioned the long-term supply of DDR3, DDR4, including DRAM chips and bare wafers.
This involves the domestic DDR4 or purple group subsidiary of the country purple core, which owns Xi'an purple core, Shenzhen State Micro, Purple Tongchuang and other companies.According to the official website, 'purple core is the Group's semiconductor industry listed company, Focusing on the field of IC design and development, it is a leading supplier of integrated circuit chip design and system integration solutions in China, insisting on sound operation, continuous innovation and open cooperation. 'Their DRAM memory technology comes from the acquisition of Qimonda Xi'an company, so with DDR memory technology research and development, production capacity.
Previously rumored that domestic DDR4 memory is actually DDR3 memory, Xi'an National core, the company also said DDR4 DDR3 memory is still in production, is still in development, but the official website of Xi'an National core mentioned in the long-term availability of various DDR Memory, including SDR, DDR2, DDR3 and DDR4 memory means that they are now capable of producing DDR4 memory chips and modules.
However, the problem, click on this page, they provide DDR memory specifications and only DDR3, can provide the core capacity of the lowest 512Mb, up to 4Gb DDR3 chip voltage is 1.35-1.5V, the frequency is not high, the lowest 1066MHz, the highest But also 1866MHz.
