Recently, China has set two records in the field of semiconductor chips: the world’s first mass production of 28nm embedded RRAM image adjustment chips, and the world’s first development of a 16-bit quantum bit semiconductor microprocessor chip.
World’s first mass production of 28nm RRAM-embedded image quality adjustment chip
According to the official account of Beijing Yizhuang, the world’s first 28nm embedded RRAM (resistive random access memory) picture quality adjustment chip, developed by Chinese semiconductor company Xianxin Technology in collaboration with a domestic research institute, has been mass-produced in Beijing and adopted in a high-end mini LED TV series by a major Chinese brand.
The 28nm display chip is reported to adopt the “digital chip + embedded RRAM” technology solution. Compared with the industry mainstream chip that adopts “TCON + external FLASH memory”, this chip effectively solves problems such as the high cost of external memory devices and the slow reading speed of correction parameters.
Additionally, the chip directly integrates RRAM IP into the 28nm process node, enabling lower costs, smaller size, and improved efficiency.
According to data, this mass-produced 28nm embedded RRAM image adjustment chip is not only China’s first domestically produced 28nm display chip, but also the world’s first advanced commercial image adjustment chip that adopts 28nm embedded RRAM IP.
It has completely independent intellectual property rights. The built-in RRAM memory module and core RRAM IP technology are derived from research institutes, and the image quality adjustment algorithm is independently developed by Xianxin Technology.
HKPU develops 16-bit quantum semiconductor microprocessor chip
Recently, a research team from the Hong Kong Polytechnic University (HKPU) successfully developed the world’s first 16-bit quantum bit semiconductor microprocessor chip, providing a new solution for simulating large-scale and complex molecular spectra.
HKPU explained that the team simulated molecular vibrational spectra using a linear photonic network and a compressed vacuum quantum light source, a 16-bit quantum microprocessor chip that was fabricated and integrated on a single chip.
In addition, the team developed a complete system including the photonic-electronic-thermal package for the quantum photon microprocessor chip and control module, driver software and user interface, and programmable underlying quantum algorithms. The developed quantum computing system can be applied to a variety of computational models.
Quantum microprocessors can be used to handle complex tasks such as faster and more accurate simulations of large protein structures and optimizing molecular reactions.
Dr. Zhu Huihui, postdoctoral researcher and first author of the research paper, said that this method breaks through traditional limitations, enabling earlier practical molecular simulations and potentially realizing quantum acceleration in related quantum chemistry applications.
In addition to Hong Kong Polytechnic University, collaborating institutions are reportedly Nanyang Technological University, City University of Hong Kong, Beijing Technological University, Southern University of Science and Technology, the Institute of Microelectronics (IME), and Chalmers University of Technology in Sweden.
