According to Di Ventra, despite his new technology's futuristic promise, "memcomputers can be built with standard technology and operate at room temperature. This puts them on a completely different level of simplicity and cost in manufacturing compared to quantum computers."
In short, a big problem with modern computers is that they store data and solve problems with it in two entirely different areas: the memory, and the central processing unit (CPU). "To make a quick comparison: our own brain expends about 20 watts to perform 10^16 operations per second," he says, while a supercomputer would require 10 million times more power to do the same number of operations.
at the core of Di Ventra's machine are what he calls memprocessors.A classical transistor's job basically boils down to one thing, either letting energy through, or not, depending one what it's been told to do.A memprocessor does this exact same job, but it also physically changes some of its properties ("such as its [electrical] resistance," says Di Ventra) depending on how much energy is trying to move through.n this way, while totally functioning as a classical, data-crunching CPU, memprocessors can also be coded to store resistance-laden information at the same time.rather than hassling with a back-and-fourth data-shuffle, the internal architecture of the memcomputer essentially sets up a giant maze for electricity to run through.
