Inspired by the human brain, researchers have developed a new synaptic transistor capable of emulating some of the processes that characterize cells or structures of the human brain.
The device processes and stores information simultaneously, just like the human brain. In the most recent experiments, researchers have shown that the transistor goes beyond simple machine learning tasks for categorizing data: it is capable of associative learning.
This amazing transistor was designed by scientists from Northwestern University, Boston College and the Massachusetts Institute of Technology (MIT), all of these institutions in the United States.
Although previous research has pursued similar strategies to develop brain-like computing devices, such transistors can only operate at temperatures many degrees Celsius below zero. The new device, on the other hand, operates without problems at room temperature. In addition, it operates at high speed, consumes very little power and retains stored information even when power is removed, all of which makes it ideal for many practical applications.
The brain has a very different architecture from that of a classic digital computer. In a conventional digital computer, data goes back and forth between a microprocessor and memory, which consumes a lot of power and creates a bottleneck when trying to multitask. Instead, in the brain, memory and information processing are co-located and fully integrated, resulting in orders of magnitude better energy efficiency. The new synaptic transistor also makes memory and information processing work simultaneously to more closely mimic the brain.
Recent advances in artificial intelligence have motivated researchers to develop computers that function more like the human brain.
Conventional digital computing systems have separate processing and storage units, making data-intensive tasks consume large amounts of energy.
As smart devices continually collect massive amounts of data, researchers are eager to discover new ways to process it without consuming more and more energy. Currently, memory resistor is the most developed technology that can perform combined processing and memory functions. But memory resistors still suffer from energy-intensive switching.
