Nanostructures Bring Gains for Phase Change Memory

Cars That Think

Engineers in the United States and Taiwan say they have demonstrated a promising new twist on nonvolatile memory that’s small enough, miserly when it comes to energy, and works at low enough voltage that it could boost the abilities of future processors. volts and switch in about 40 nanoseconds while consuming less than 1.5 picojoules.

3 Ways 3D Chip Tech Is Upending Computing

Cars That Think

In CPUs, these links have mostly been so-called 2.5D, where the chiplets are set beside each other and connected using short, dense interconnects. But to sling truly huge volumes of data around as if it were all on the same chip, you need even shorter and denser connections, and that can be done only by stacking one chip atop another.
