Magnetic Logic Makes for Mutable Computer Chips
A new alternative transistor relies on a semiconductor that can be switched with magnetism instead of electricity. The approach could help make circuitry more malleable and lead to more efficient and reliable gadgets
But Johnson notes that magnetism is already catching on in circuit design: some advanced devices are beginning to use a magnetic version of random access memory, a type of memory that has historically been built only with conventional transistors. “I think a shift is already under way,” he says.
