DDR4 chip based on third-generation 10nm class technology

29.03.2019

Samsung said it was the first in the industry to develop 4Gb Double Data Rate 4 (DDR8) memory chips based on third-generation 10nm class manufacturing technology. At the same time, it is noted that only 16 months have passed since the start of mass production of the same chips, but based on the production technology of the 10-nanometer class of the second generation. During this time, the development of the 8Gb DDR4 chip based on 10nm-class technology without the use of EUV photolithography has pushed the limits of DRAM scaling.

Thanks to the introduction of new technology, production efficiency has been increased by 20% compared to the previous generation technology. After testing the new 8 GB memory modules with processor manufacturers, Samsung will actively collaborate with global customers to provide a wide range of affordable solutions.

Mass production of 4Gb DDR8 memory chips based on third-generation 10nm class manufacturing technology will begin in the second half of this year, and high-performance computers and servers with such chips will hit the market as early as 2020.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Interface for office equipment 28.11.2006

Three-channel, 16-bit analog interface chip (analog front end, AFE) from National Semiconductor, according to the manufacturer, can significantly improve the performance of multifunctional devices (MFPs) focused on office use.

For example, color copy speeds are estimated by National Semiconductor to be in excess of 40 pages per minute. Operating at frequencies up to 45 MHz, the LM98714 is the first AFE to integrate a programmable time clock for charge-coupled devices (CCD) and contact image sensors (CIS), as well as a low-voltage serial interface with using difference signals (LVDS).

Today's high-speed copiers capable of making color copies are quite bulky and expensive. The LM98714 is expected to enable cost-effective and fast desktop-sized devices. The set of functions implemented in the microcircuit makes it possible to place the AFE directly on the CCD board, optimizing the design of the copier, reducing the level of electromagnetic interference and increasing its speed.

The LM98714 has the industry's best signal-to-noise ratio of 74dB and the industry's lowest power consumption of 505mW. It is expected that the novelty will find application in copiers, MFPs, devices for counting banknotes, scanners, faxes. The chip is available in a 48-pin TSSOP package.
