The Energy Efficient RRAMs

Engineers at Stanford are making 3-D memory chips that can offer faster and more energy efficient solutions for computer memory. These are the Resistive random Access Memory or RRAMs, which are based on a new semiconductor material. It stores data based on temperature and voltage. However, the actual workings of RRAMs continued to be a mystery until a team at Stanford used a new tool for their investigations. They found the optimal temperature range to be lower than they had expected. This could Read more [...]

Adding Memory to the Raspberry Pi

Although the memory onboard the Single Board Computer Raspberry Pi or RBPi is sufficient for most applications, some may feel the necessity of expanding the storage capacity. The options provided on the RBPi are limited, as the USB ports often engage a keyboard, a mouse or a game controller and the SD card slot holds only a single device. The most obvious option for expanding the storage capacity on the RBPi is through the USB ports. However, tying up ports with a USB hard disk drive or flash Read more [...]

What is 3D Flash Memory?

Slowly, but steadily, the memory market is veering away from magnetic disc storage systems to solid-state drives or SSDs. Not only are prices falling fast, manufacturers are producing SSDs with improved technologies, leading to denser memories, higher reliability and lower costs. For example, Samsung has recently announced SSD and systems designs that will drive their new 3-D NAND into mass markets. Samsung's latest SSDs are the 850 EVO series. According to Jim Eliot, a marketing executive for Read more [...]

The 64-bit x86 SOC from AMD

Advanced Micro Devices or AMD is offering a new Embedded, R-Series SOC processor. Targeted at a range of application markets, the System-On-Chip processor will handle industrial control and communication networking along with digital signage, high-end gaming and media storage. The new AMD device follows the Platform System Architecture, Specification 1.0, of the HSA Foundation. The Heterogeneous System Architecture offers greater efficiency in parallel processing. In the new Embedded R-Series Read more [...]

Non-Volatile Memory from Carbon

So far, many problems have inhibited development of carbon based memory devices. Not any more, as IBM and the EMPA have solved those problems and come up with the possible use of oxygenated amorphous carbon for non-volatile memory applications. The new non-volatile memory is based on a Redox reaction that takes place in thin films of oxygenated amorphous carbon known as a-COx. The film is a process of PVD or Physical Vapor Deposition. EMPA, the Swiss Electron Microscopy Center and IBM, Zurich, Read more [...]
