Series production of HBM2E memory

02.07.2020

SK hynix has announced the start of full-scale mass production of high-speed DRAM memory or HBM2E.

With a 1024-bit bus running at 3,6 Gb/s per lane, HBM2E memory delivers 460 GB/s of bandwidth, outperforming HBM2 memory by 50%.

An HBM2E stack can have up to eight 16Gb dies connected using TSV (Through Silicon Via) technology, so that the maximum memory capacity reaches 16GB. This is twice as much as in the case of HBM2 memory.

According to SK Hynix, HBM2E is the "optimum solution" for next-generation AI memory systems, deep learning accelerators and supercomputers. It is expected that it will find application in an exascale supercomputer, which will be able to take fundamental and applied scientific research to a new level.

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, ... >>

Genetically modified maggots heal wounds 19.05.2016

Scientists at the University of North Carolina once again remembered the old method of treating wounds. They genetically modified the larvae to clean human wounds and secrete a reagent that accelerates healing.

In the past, doctors used carrion green fly larvae as a treatment tool. The larvae ate the dead tissue and left the living tissue, moreover, they secreted antimicrobial substances that kept the wound clean. In general, the method was cheap and effective, but not fast. Clinical trials have shown that maggots do not speed up wound healing, but new genetically engineered creatures could change that.

Human platelet growth factor is a signaling molecule that causes cells to divide rapidly. Also, as experiments have shown, it helps wounds heal. Researchers have already used insects to produce growth factor, but the technique has never been used on fly larvae. Biologists from North Carolina made two "batches" of larvae. One was modified to produce a factor when heated to 37 degrees Celsius. The other produced the necessary substance if she followed a diet that did not include the antibiotic tetracycline.

The heated larvae really began to produce a growth factor, but they never isolated it from their bodies, but a group of larvae purified from tetracycline abundantly excreted the required substance in body secretion and waste products. Although the larvae have not yet been tested on human wounds, the researchers believe that these insects will both clean wounds and heal them, greatly reducing the time it takes for flesh to heal.

Such a remedy will especially help people with diabetes who have non-healing ulcers on their legs. Although the thought of worms poking around in open wounds is unpleasant, but if they halve the healing time, then the remedy will be popular.
