RESEARCH & DEVELOPMENT  

fsuResearchers Take Computer Memory for a Spin
Using unique equipment developed by the National High Magnetic Field Laboratory, an international team of researchers has used the spin of atomic nuclei in silicon to store information for longer than a minute and a half. More remarkable still, the team showed that the information can be read out electronically — a key step toward the development of faster conventional computer and superfast “quantum” computers.

As demand for smaller and faster electronics increases, many scientists are focusing their efforts in the emerging field of “spintronics,” where the magnetic character, or spin, of electrons and nuclei are used to store information. While other researchers have shown that spin information can be processed in silicon, the material on which modern electronics and computing is based, until now, no effective way to both store and read out the information has been found.

“Finding a system compatible with silicon, the main material used in the semiconductor industry, is particularly useful as it has the potential to be incorporated into existing technology,” said McCamey, lead author on the paper. “We could then integrate spin based information storage and processing devices onto a single chip.”

This is a new way of storing energy, said Boehme, a senior author on the paper. “The length of spin memory we observed is more than adequate to create memories for computers.”

Adequate, yes. But feasible? Not anytime soon, the authors caution. The nuclear spin storage-and-read-out apparatus works only at a few degrees Kelvin, or just slightly above absolute zero — the temperature at which even atoms almost stop moving. And it must be surrounded by high magnetic fields roughly 200,000 times stronger than Earth’s.

“Yes, you could immediately build a memory chip this way, but do you want a computer that has to be operated at 458 degrees below zero Fahrenheit and in a big national magnetic laboratory environment?” said Boehme. “First we want to learn how to do it at higher temperatures, which are more practical for a device, and without these strong magnetic fields to align the spins.”

The researchers used unique equipment for controlling electronic and nuclear spins in high magnetic fields and at very low temperatures to achieve their findings. The equipment was developed and built by van Tol and colleagues in the Mag Lab’s Electron Magnetic Resonance user program.

“The high magnetic fields we use enable the electron spins to be lined up, initializing them so they are ready to store information” said van Tol. “We now show that we can line up the nuclear spins too.”

“Electrical detection of electron spins is also the leading approach for detecting quantum information in silicon” said Morley. “Future experiments could use this method to study quantum information stored in nuclear spins.”

The study was funded by the National High Magnetic Field Laboratory, the National Science Foundation, the Australian Research Council, Britain’s Engineering and Physical Sciences Research Council and the Royal Commission for the Exhibition of 1851, a British funding agency led by Prince Philip.

allegroAllegro MicroSystems, Inc. Introduces a New User-Programmable Linear Hall-Effect Sensor IC
Allegro MicroSystems, Inc. has introduced a new user-programmable linear Hall-effect sensor IC with pulse width modulated output. The A1356 complements Allegro’s existing line of linear devices with PWM outputs by offering a device with significantly higher carrier frequency of 2 kHz. This new device targets gear detection, fork, clutch and neutral positions within the automotive market in addition to key applications within the industrial market.

The A1356 device is a high precision, user programmable, Hall-effect linear sensor with a pulse width modulated (PWM), open collector output. The duty cycle (DC) of the PWM output signal (freq: 2 kHz) is proportional to an applied magnetic field. The A1356 device converts an analog signal from its internal Hall sensor element to a digitally encoded PWM output signal. The coupled noise immunity of the digitally encoded PWM output is far superior to the noise immunity of an analog output signal, particularly when the signal needs to travel over long wires within the system.

The BiCMOS, monolithic circuit inside of the A1356 integrates a Hall element, precision temperature-compensating circuitry to reduce the intrinsic sensitivity and offset drift of the Hall element, a small-signal high-gain amplifier, proprietary dynamic offset cancellation circuits, and PWM conversion circuitry. The dynamic offset cancellation circuits reduce the residual offset voltage of the Hall element, which is normally caused by device over molding, temperature dependencies, and thermal stress. The high-frequency offset cancellation (chopping) clock allows for a greater sampling rate, which increases the accuracy of the output signal and results in faster signal processing capability.

The design and manufacturing flexibility of the A1356 is realized through user programmable: gain, quiescent duty cycle and carrier frequency. The device can be set up in a magnetic circuit and programmed with a train of serial pulses. Once the appropriate parameters have been selected, the codes can be locked for one-time programming. In this manner, manufacturing tolerances can be reduced and the assembly process can be simplified.

The A1356 sensor is provided in a lead (Pb) free, 3-pin, single inline package (KB suffix), with 100 percent matte tin leadframe plating.  It is priced at $1.45 in quantities of 1,000.
