Elucidation of the Behavior of a Resistive Random Access Memory by Analyzing Current Noise

AIST has developed a technique to study oxygen vacancy states in a resistive random access memory (ReRAM) without damaging the memory functions. An identical device can be used to investigate both conventional and low-power operation modes, making it possible to compare the oxygen vacancy states under different conditions. Only in a high resistance state during the low-power operation, the frequency dependence of the current noise shows that a small number of oxygen vacancies are present. The researchers have concluded that the reduction of oxygen vacancies which contribute to electrical conduction is required to further reduce the power consumption of ReRAMs.

Development of a biosensor that can easily detect viruses at very low concentrations

AIST has developed an external force-assisted near-field illumination biosensor (EFA-NI biosensor) that can detect small amounts of bio-substances, including viruses, in contaminant containing samples such as secondary treated sewage water. Magnetic beads and fine particles (polystyrene beads) that scatter light are attached to a target bio-substance, and “moving light spots” are made with external magnetic force and near-field illumination for detection. It is possible to detect bio-substances without removing contaminants using the new “movement” distinction method that was not present in the conventional method. With the goal of preventing infection by highly infectious viruses, AIST researchers aim to improve detection sensitivity.

Spintronics Research Center

Creating innovative green IT based on spintronics

The rapid development of IT society is accompanied with a large increase in the power consumption of electronic devices. To reduce the total power consumption of IT appliances, power consumed during input "standby time" as well as active power have to be significantly reduced. To achieve this, it is essential to develop nonvolatile memory, which retains data even after the power is turned off. We are developing low-power-consuming, high-speed, and highly-reliable nonvolatile memory and spin logic device based on spintronics technology. Moreover, we are also developing novel spintronic devices such as nano-sized microwave oscillator called Spin-Torque Oscillator (STO), high-speed physical number generator named Spin Dice, and spin optical devices.
