Using advanced imaging techniques, an international team led by Penn State researchers found that the material that a semiconductor chip device is built on, called the substrate, responds to changes in electricity much like the semiconductor on top of it.
Researchers have found two novel types of attacks that target the conditional branch predictor found in high-end Intel processors, which could be exploited to compromise billions of processors currently in use. The multi-university and industry research team led by computer scientists at University of California San Diego will present their work at the 2024 ACM ASPLOS Conference that begins tomorrow.
Researchers have studied the operation of a small device fabricated in the write gap of a hard disk drive’s write head to extend its recording density. The device is based on microwave-assisted magnetic recording. This technology, reported in Journal of Applied Physics, uses a spin-torque oscillator, which causes the magnetic particles of the recording medium to wobble. This makes them much easier to flip over when the write head applies a recording magnetic field in the writing process.
The development of a new method to make non-volatile computer memory may have unlocked a problem that has been holding back machine learning and has the potential to revolutionize technologies like voice recognition, image processing and autonomous driving.
