The massive growth of data centers that consume enormous amounts of energy has contributed significantly to power shortages worldwide. With rising demand for faster and more intelligent computers and devices, there is a pressing need to develop alternatives to traditional electronic components that will make these devices more energy-efficient.

In two recent studies, researchers at the Centre for Nano Science and Engineering (CeNSE), IISc, report the development of a highly energy-efficient computing platform that offers promise in building next-generation electronic devices.

Instead of using complementary metal-oxide semiconductors (CMOS) which are the building blocks of most electronic circuits today, th...

Device can be reconfigured multiple times simply by changing applied voltage. In a discovery published in the journal Nature, an international team of researchers has described a novel molecular device with exceptional computing prowess.

Reminiscent of the plasticity of connections in the human brain, the device can be reconfigured on the fly for different computational tasks by simply changing applied voltages. Furthermore, like nerve cells can store memories, the same device can also retain information for future retrieval and processing.

“The brain has the remarkable ability to change its wiring around by making and breaking connections between nerve cells...

The design could advance the development of small, portable AI devices. MIT engineers have designed a “brain-on-a-chip,” smaller than a piece of confetti, that is made from tens of thousands of artificial brain synapses known as memristors — silicon-based components that mimic the information-transmitting synapses in the human brain.

The res...

Left: A simplified representation of a small part of the brain: neurons receive, process and transmit signals through synapses. Right: a crossbar array, which is a possible architecture of how this could be realized with devices. The memristors, like synapses in the brain, can change their conductivity so that connections can be weakened and strengthened.

Computer bits are binary, with a value of 0 or 1. By contrast, neurons in the brain can have all kinds of different internal states, depending on the input that they received. This allows the brain to process information in a more energy-efficient manner than a computer...
