FUJITSU develops RFID chip with FRAM memory

29.08.2005

Fujitsu has announced the FerVID MB89R119 chip, designed for use in increasingly popular wireless identification (RFID) systems.

The main difference between the new development and existing implementations is the use of ferroelectric memory (FRAM). Its volume is quite small - only 256 bytes, but this is quite enough for identification tasks. Compared to the EEPROM type memory commonly used in such chips, FRAM has an advantage in read speed up to 50 times, and in write speed - twice.

In addition, the use of FRAM eliminates the need for the burn circuits required in EEPROM, which reduces the area occupied on the substrate. The MB8 9R119 chip is manufactured using a 0,35 micron process, operates at a frequency of 13,56 MHz, has a range of 70 cm, and a bandwidth of 26,48 Kbps.

Samples are available now at a price of $0,46, mass production will begin on August 1, and the planned output is 5 million units per month.

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 ... >>

Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

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, ... >>

Compact device for visualization of brain activity 26.03.2018

British scientists have found a way to miniaturize a huge magnetoencephalograph - a device that allows you to register changes in the activity of neurons with an interval of thousandths of a second and accurately determine in which part of the brain the work is going on.

One can look into the living brain by removing the skull cap or by drilling holes in it for electrodes (this is sometimes done with laboratory animals), and by several non-invasive (without penetration) methods. Electroencephalographs (EEG) record the electrical activity of the brain, removing potential fluctuations from the scalp; this method shows changes in brain function very quickly, but it cannot be used to determine exactly where in the brain activity has increased or subsided. Functional magnetic tomographs (fMRI) show to which parts of the brain blood flows and from which it drains (it is assumed that blood flows to "working" groups of neurons). The localization accuracy of fMRI is high, but the temporal resolution is low - the most modern devices give a maximum of one picture per second, and the speed of neuron interaction is much higher.

Magnetic encelographs measure fluctuations in the magnetic field, which excite the activity of neurons. These devices give a high spatial and temporal expansion, but they have their drawbacks: the main one is that they are extremely bulky. A person whose head is placed in such a device needs to sit still and not move. Healthy adults have no problem with this, but things get worse when scientists work with children or with people who, due to illness, are unable to keep their heads upright. In addition, it is possible to observe the work of the brain with the help of these devices only in the laboratory.

A new development of British scientists and engineers can facilitate the work of neuroscientists: the magnetoencephalograph they have created (so far a prototype) is a helmet with wires. Wearing such a device, a person can safely move and move his head; its body is 3D printed from a pre-prepared digital model of the subject's head, so it can be securely attached to the head of a person of any age. The creators of the device expect that their development will help children and adolescents suffering from mental disorders, and neuroscientists will be able to observe the brain in situations that cannot be recreated in the laboratory.
