Spin-RAM for Normally-Off Computer

2011 11th Annual Non-Volatile Memory Technology Symposium Proceeding, 2011
Spin-RAM technologies for operation speed faster than 30 ns, memory capacity larger than 1 Gbits and practically infinite read/write endurance have been developed by using magnetic tunnel junctions with perpendicular magnetization layers. Combination of Spin-RAM and power-gating technology will enable ultra low power computer called Normally-Off ...

Threshold voltages of normally off MESFET's

IEEE Transactions on Electron Devices, 1972
The threshold voltage of "normally off" Si-MESFET's for simple dc-coupled circuits is defined and computed with a two-dimensional device model, taking into account carrier velocity saturation and diffusion. The influence of the main parameters, gate length, conducting-layer thickness, and doping is investigated outside the range of Shockley's equations.

Normally-Off Mesfet Analogue Circuits

16th European Microwave Conference, 1986, 1986
A very small (0.04 mm2) monolithic DC to 2GHz, input/output matched, amplifier using enhancement mode GaAs MESFET's has been realized, to demonstrate the analog circuits capability of this type of transistor. The gain of the amplifier is 12dB, its noise factor is 2dB.

Normally-off computing for IoT systems

2015 International SoC Design Conference (ISOCC), 2015
It is important to thoroughly reduce energy consumption for IoT systems. Normally-Off is a way of computing which aggressively powers off components of computer systems when they need not to operate. Recently, new non-volatile memories (NVMs) have appeared. We introduce normally-off computing using these NVMs.

Normally-off technology at Philips microwave

III-Vs Review, 1991
Abstract Philips Microwave GaAs Foundry and ASIC Design Centre at Limeil, near Paris, has a calibrated 0.7μm ERO7AD process which is particularly well suited to low dc power analogue and digital ICs. In a clear demonstration of the capability of the process, new structures have been used to improve the performance of a family of low noise amplifiers.

Implementation of normally-off function for TOPPERS/ASP kernel

2013 IEEE 2nd Global Conference on Consumer Electronics (GCCE), 2013
This paper proposes a normally-off embedded system. The idea behind this system is it turns the power off when the system is idle. Volatile devices, however, cannot maintain their own internal information when they are powered off. So, we use non-volatile RAM (NVRAM) to save the internal information.

Nanofabrication of normally-off GaN vertical nanowire MESFETs

Nanotechnology, 2019
Abstract Gallium nitride (GaN) all-around (wrap) gate vertical nanowire (V-NW) field-effect transistors (FETs) are favorable for enhanced electrostatic control of the gate and selectivity for normally on/off operation. In this work, GaN V-NW FETs with a Schottky barrier gate (V-NW MESFETs), were fabricated for the

Technologies for normally-off GaN HEMTs

2020
This chapter reviews the current technologies for normally-off GaN-based HEMTs. First, the HEMT "cascode" approach is briefly described, highlighting advantages and limitation of this design.Then, after illustrating the recessed gate HEMT and the fluorinate gate approach, the focus is put on the recessed gate hybrid metal insulator semiconductor high ...

Technologies for Realizing Normally-Off Computing

2017
Normally-off computing relies on device technologies, architectural and activity management technologies. To realize normally-off computing systems, details of each technology should be studied. Device technologies provide component that has as small BET as possible by minimizing energy overhead. Architectural technologies combined several devices that

Spintronic normally-off heterogeneous system-on-chip design

2018 Design, Automation & Test in Europe Conference & Exhibition (DATE), 2018
One of the major challenges in device down-scaling is the increase in the leakage power, which becomes a major component in the overall system power consumption. One way to deal with this problem is to introduce the concept of normally-off instant-on computing architectures, in which the system components are powered off when they are not active.
