Secure SSD can perform encryption key erase in under 30ms
With data security threats increasing, Microsemi has introduced its 2nd gen highly secure 64GB SSD, specifically designed for market applications where data protection is of the utmost importance. It overcomes malicious attack concerns with Microsemi’s factory firmware lockdown technology preventing covert firmware repurposing. Offered in a 32x28mm BGA package, the SSD is optimised for embedded computers in harsh environments.
The art of DRAM module testing
DRAM technology is well known and components are fully standardised products, which are manufactured with low cost materials and assembly lines. So why are there differences in quality and price anyway? By Ulrich Brandt, Head of Business Unit DRAM Products at Swissbit AG.
Flash memories target wearables, low power applications
The new ultra-low power MX25R family of Serial NOR Flash devices from Macronix are on sale at distributor Ineltek UK. Targeting wearables and long battery-life applications, the devices offer standard features designers have come to expect in Serial Flash, with many added benefits including deep standby currents measured in nanoamps.
MRAM device offers SRAM-compatible 35ns read/write timing
Offering a significantly decreased package footprint size, e2v has announced the release of a stacked-package 32Mb MRAM-based product, the highest density MRAM device in the industry. The EV5A16B is a stacked solution, featuring two 16Mb MRAM devices from Everspin Technologies, and is offered in a 54-pin stacked-package TSOP.
SQI interfaces provide the 'industry's fastest' erase times
A family of SQI (Serial Quad I/O) interface SuperFlash memory devices has been introduced by Microchip. The SST26VF family is comprised of a 16Mb model, a 32Mb model and a 64Mb model, all of which have been manufactured using Microchip’s CMOS SuperFlash technology.
Memory card focuses on dashboard cameras,home video
As a finale to the Mobile World Congress in Barcelona, SanDisk introduced the company’s first high endurance microSDXC memory card built to withstand up to 10,000 hours of Full HD Video1 recording. The new technology has proven itself to enable the company to reach a new milestone -- a 64GB2 microSDXC card that allows consumers to write and rewrite up to 10,000 hours of Full HD recording.
Unified theoretical description of the behaviour of skyrmions is released
Magnetic vortex structures, so-called skyrmions, could in future store and process information very efficiently. They could also be the basis for high-frequency components. For the first time, a team of physicists succeeded in characterising the electromagnetic properties of insulating, semiconducting and conducting skyrmion-materials and developed a unified theoretical description of their behaviour, thus laying the foundation for future electro...
High-speed multiplexer targets DDR4 NVDIMM technology
Integrated Device Technology has announced a high-speed multiplexer targeting the nascent NVDIMM (non-volatile dual in-line memory module) ecosystem. The 12-bit bus switch/multiplexer features a make-before-break circuit that prevents glitches when switching and AC and DC parameters optimised for DDR4, enabling the highest possible memory channel performance for NVDIMMs even when intermixed with other DIMM types.
Tablet demand reduces DRAM bit volume growth
IC Insights’ recently released 2015 edition of 'The McClean Report' shows that DRAM bit volume grew by an average of 67% per year from 1995-2005. In the 10 years since then, however, bit volume growth has averaged 43% per year (see figure below). A worldwide economy mired in recession reduced bit volume growth to an all-time low of 21% in 2009, a big contrast to the 1990s when annual DRAM bit volume growth remained above 70%.
