Paving the way to six-state magnetic memory
Computers are often described with "ones and zeros," referring to their binary nature: each memory element stores data in two states. But there is no fundamental reason why there should be just two. In a study, researchers have designed a magnetic element that has six stable magnetic states, which paves the way toward realising a six-state magnetic memory element.
Memory chip can store up to 3 bits per cell
For the first time, scientists at IBM Research have demonstrated reliably storing 3 bits of data per cell using a relatively memory technology known as phase-change memory (PCM). The current memory landscape spans from venerable DRAM to hard disk drives to ubiquitous flash. But in the last several years PCM has attracted the industry's attention as a potential universal memory technology based on its combination of read/write speed, enduranc...
MicroSD cards cost effective against NAND flash
The new industrial-grade SuperMLC UHS-I Speed Class 1 (U1) microSD cards from Transcend have capacities of 4GB, 8GB, 16GB and 32GB. Between SLC and MLC NAND flash, the new SuperMLC technology features a cost-effective solution yet with nearly equivalent performance to SLC NAND flash. The SuperMLC is ideal for industrial applications and is available at distributor Rutronik.
Hafnium oxide material could store non-volatile memory
Scientists from MIPT have succeeded in growing ultra-thin (2.5-nanometre) ferroelectric films based on hafnium oxide that could potentially be used to develop non-volatile memory elements called ferroelectric tunnel junctions. The results of the study have been published in the journal ACS Applied Material Interfaces. Scientists all over the world are trying to develop faster and more compact storage devices. The ideal would be a universal memory...
Memory interface devices qualified for DDR4 enterprise DIMMs
IDT announced that its 4RCD0124K register, 4DB0226KA3 data buffer and TSE2004 temperature sensor components are fully qualified by memory eco-system leaders, including Intel, Dell and Micron, for DIMM applications on Intel Xeon processor E5-2600 v4 product family-based server and storage systems.
Technique could store digital data using DNA molecules
A technique developed by University of Washington and Microsoft researchers could shrink the space needed to store digital data that today would fill a supermarket down to the size of an ice cube. The team of computer scientists and electrical engineers has detailed one of the first complete systems to encode, store and retrieve digital data using DNA molecules, which can store information millions of times more compactly than current archival te...
Making memories
From changing the phase of glass to moving copper ions around, Sally Ward-Foxton reports on some of the most novel and interesting memory technologies to come to market in recent months.
SSD modules obtain the maximum possible endurance
Swissbit has released a product series of M.2 SSD (solid state drive) modules. The SATA III durabit SSDs use MLC flash memory together with special hardware and firmware features to obtain the maximum possible endurance, data retention and performance from MLC technology. Compliant with the latest SATA III (6.0 Gb/s) interface specification, these drives meet the requirements of today’s industrial, network/communication and automotive appli...
Structure magnetic memory device uses magnetisation switching
The research group of Professor Hideo Ohno and Associate Professor Shunsuke Fukami of Tohoku University has developed a new-structure magnetic memory device utilising spin-orbit- torque-induced magnetisation switching. For these two decades, much effort has been devoted to the development of magnetic random access memories (MRAMs), which store information as the magnetisation direction of a magnet.
Alternative ways to archive data for supercomputers
Seagate Technology and Los Alamos National Laboratory (Los Alamos) are researching a new storage tier to enable massive data archiving for supercomputing. The joint effort is aimed at determining innovative new ways to keep massive amounts of stored data available for rapid access, while also minimising power consumption and improving the quality of data-driven research.
