Abstract: Embodiments are directed to systems and methods for providing light communication (LC) for an aircraft. An LC transmitter is mounted on an aircraft fuselage and is configured to broadcast light signals within a defined region outside the aircraft. An LC receiver mounted on the aircraft fuselage is configured to receive light signals broadcast by a remote LC device. A controller is configured to manage LC signals in the aircraft, and an interface is provided between the controller and an aircraft data network. The light signals may be in a visible light spectrum, an invisible light spectrum, or both. The remote LC device may be, for example, a ground station, an aircraft, a ground vehicle, a ship, a building, or a portable transmitter.

Abstract: An interconnected stack of one or more Dynamic Random Access Memory (DRAM) die has a base logic die and one or more custom logic or processor die. The processor logic die snoops commands sent to and through the stack. In particular, the processor logic die may snoop mode setting commands (e.g., mode register set—MRS commands). At least one mode setting command that is ignored by the DRAM in the stack is used to communicate a command to the processor logic die. In response the processor logic die may prevent commands, addresses, and data from reaching the DRAM die(s). This enables the processor logic die to send commands/addresses and communicate data with the DRAM die(s). While being able to send commands/addresses and communicate data with the DRAM die(s), the processor logic die may execute software using the DRAM die(s) for program and/or data storage and retrieval.

Abstract: An integrated circuit (IC) memory device includes an array of storage cells configured into multiple banks. Interface circuitry receives refresh commands from a host memory controller to refresh the multiple banks for a first refresh mode. On-die refresh control circuitry selectively generates local refresh commands to refresh the multiple banks in cooperation with the host memory controller during a designated hidden refresh interval in a second refresh mode. Mode register circuitry stores a value indicating whether the on-die refresh control circuitry is enabled for use during the second refresh mode. The interface circuitry includes backchannel control circuitry to transmit a corrective action control signal during operation in the second refresh mode.

The method may use an ambient ionisation method.

Abstract: Disclosed is a memory system that has a memory controller and may have a memory component. The memory component may be a dynamic random access memory (DRAM). The memory controller is connectable to the memory component. The memory component has at least one data row and at least one tag row different from and associated with the at least one data row. The memory system is to implement a cache having multiple ways to hold a data group. The memory controller is operable in each of a plurality of operating modes. The operating modes include a first operating mode and a second operating mode. The first operating mode and the second operating mode have differing addressing and timing for accessing the data group. The memory controller has cache read logic that sends a cache read command, cache results logic that receives a response from the memory component, and cache fetch logic.

Abstract: A memory system includes two or more memory controllers capable of accessing the same dynamic, random-access memory (DRAM), one controller having access to the DRAM or a subset of the DRAM at a time. Different subsets of the DRAM are supported with different refresh-control circuitry, including respective refresh-address counters. Whichever controller has access to a given subset of the DRAM issues refresh requests to the corresponding refresh-address counter. Counters are synchronized before control of a given subset of the DRAM is transferred between controllers to avoid a loss of stored data.

Abstract: An example apparatus includes a light source, first and second polarizers, an image sensor, a filter, and control circuitry. The light source outputs a light beam, and the first polarizer passes first polarized light from the output light beam and toward a sample. The image sensor collects light reflected from the sample responsive to the passed first polarized light. The second polarizer passes second polarized light from the reflected light and toward the image sensor. The filter selectively passes the reflected light in a visible light range and near infrared range (NIR) light range toward the image sensor. The control circuitry causes the first and second polarizers to adjust to different polarization angles, and collects the image data of the sample from the reflected light.

Abstract: An interconnected stack of one or more Dynamic Random Access Memory (DRAM) die also has one or more custom logic, controller, or processor die. The custom die(s) of the stack include direct channel interfaces that allow direct access to memory regions on one or more DRAMs in the stack. The direct channels are time-division multiplexed such that each DRAM die is associated with a time slot on a direct channel. The custom die configures a first DRAM die to read a block of data and transmit it via the direct channel using a time slot that is assigned to a second DRAM die. The custom die also configures the second memory device to receive the first block of data in its assigned time slot and write the block of data.

Abstract: A stacked processor-plus-memory device includes a processing die with an array of processing elements of an artificial neural network. Each processing element multiplies a first operand—e.g. a weight—by a second operand to produce a partial result to a subsequent processing element. To prepare for these computations, a sequencer loads the weights into the processing elements as a sequence of operands that step through the processing elements, each operand stored in the corresponding processing element. The operands can be sequenced directly from memory to the processing elements or can be stored first in cache. The processing elements include streaming logic that disregards interruptions in the stream of operands.
