Description
Yuan Zhu and co-authors report, in a 2024 paper, a wafer-scale chip of tiny memory devices that switch with very little energy. The devices, built in crossbar grids, can store and process data in the same place, which suits brain-like computing. Past grids, though, used far more energy than real nerve junctions.
The team built the grid from silver sulfide using factory-friendly steps at low heat. Silver ions move easily in the material, so links form at very low cost, near the energy of a biological synapse. The low heat also lets the grid sit on flexible plastic. Extra design steps offset flaws that would otherwise hurt learning tasks.
