  • Patent number: 11984428
    Abstract: Apparatuses and methods for coupling semiconductor devices are disclosed. Terminals (e.g., die pads) of a plurality of semiconductor devices may be coupled in a daisy chain manner through conductive structures that couple one or more terminals of a semiconductor device to two conductive bond pads. The conductive structures may be included in a redistribution layer (RDL) structure. The RDL structure may have a ā€œUā€ shape in some embodiments of the disclosure. Each end of the ā€œUā€ shape may be coupled to a respective one of the two conductive bond pads, and the terminal of the semiconductor device may be coupled to the RDL structure. The conductive bond pads of a semiconductor device may be coupled to conductive bond pads of other semiconductor devices by conductors (e.g., bond wires). As a result, the terminals of the semiconductor devices may be coupled in a daisy chain manner through the RDL structures, conductive bond pads, and conductors.

  • Publication number: 20240111673
    Abstract: Apparatus and methods are disclosed, including memory devices and systems. Example memory devices, systems and methods include a buffer interface to translate high speed data interactions on a host interface side into slower, wider data interactions on a DRAM interface side. The slower, and wider DRAM interface may be configured to substantially match the capacity of the narrower, higher speed host interface. In some examples, the buffer interface may be configured to provide multiple sub-channel interfaces each coupled to one or more regions within the memory structure and configured to facilitate data recovery in the event of a failure of some portion of the memory structure. Selected example memory devices, systems and methods include an individual DRAM die, or one or more stacks of DRAM dies coupled to a buffer die.

  • Publication number: 20150091700
    Abstract: The present invention provides backscatter interrogators, communication systems and backscatter communication methods. According to one aspect of the present invention, a backscatter interrogator includes a data path configured to communicate a data signal; a signal generator configured to generate a carrier signal; and a modulator coupled with the data path and the signal generator, the modulator being configured to spread the data signal to define a spread data signal and amplitude modulate the carrier signal using the spread data signal, the modulator being further configured to phase modulate the carrier signal.
