  • Patent number: 11183509
    Abstract: An approach to use silicided bit line contacts that do not short to the underlying substrate in memory devices. The approach provides for silicide formation in the bit line contact area, using a process that benefits from being self-aligned to the oxide-nitride-oxide (ONO) nitride edges. A further benefit of the approach is that the bit line contact implant and rapid temperature anneal process can be eliminated. This approach is applicable to embedded flash, integrating high density devices and advanced logic processes.

  • Publication number: 20210344267
    Abstract: Communicating fault conditions between primary-side and secondary-side controllers of a Universal Serial Bus Power Delivery (USB-PD) device is described. The primary-side controller receives a control signal from the secondary-side controller across a galvanic isolation barrier. The primary-side controller converts the control signal into a first pulse signal and applies the first pulse signal to control a primary-side switch. When the primary-side controller detects that a first fault condition has occurred, the primary-side controller communicates a first information signal about the first fault condition to the secondary-side controller across the galvanic isolation barrier. The first information signal is generated by converting the control signal into a second pulse signal having a different pulse width than the first pulse signal. The primary-side controller applies the second pulse signal to control the primary-side power switch.
