  • Wafer level package without sidewall cracking
    Patent number: 9318405
    Abstract: A wafer level package device may include a molding compound that encapsulates a substrate, a back end of line and front end of line layer on the substrate and a passivation layer of a redistribution layer without encapsulating a metal layer on the passivation layer. The molding compound may eliminate sidewall chipping and cracking as well as reduce the need for back side lamination.

  • Method and apparatus of probabilistic programming multi-level memory in cluster states of bi-stable elements
    Patent number: 9135976
    Abstract: A probabilistic programming current is injected into a cluster of bi-stable probabilistic switching elements, the probabilistic programming current having parameters set to result in a less than unity probability of any given bi-stable switching element switching, and a resistance of the cluster of bi-stable switching elements is detected. The probabilistic programming current is injected and the resistance of the cluster state detected until a termination condition is met. Optionally the termination condition is detecting the resistance of the cluster of bi-stable switching elements at a value representing a multi-bit data.
