Abstract: A dynamic random access memory (DRAM) device includes functions configured to aid with operating the DRAM device as part of data caching functions. The DRAM is configured to respond to at least two types of commands. A first type of command (cache data access command) seeks to access a cache line of data, if present in the DRAM cache. A second type of command (cache probe command) seeks to determine whether a cache line of data is present, but is not requesting the data be returned in response. In response to these types of access commands, the DRAM device is configured to receive cache tag query values and to compare stored cache tag values with the cache tag query values. A hit/miss (HM) interface/bus may indicate the result of the cache tag compare and stored cache line status bits to a controller.

One or more tubular members extend from the electrode body and define a lumen terminating in a distal opening. The electrode assemblies carry a reservoir containing a conductive fluid or gel. The reservoir is in fluid communication with the lumens in the tubular members, and the electrode assemblies are typically supported on a backing which may optionally be configured as a headband. Systems are for tracking patient movement may be used in combination with the electrode carrier system.

Abstract: The present disclosure generally relates to user interfaces for displaying remote content.

Abstract: A laser surgery system includes a light source, an eye interface device, a scanning assembly, a confocal detection assembly and preferably a confocal bypass assembly. The light source generates an electromagnetic beam. The scanning assembly scans a focal point of the electromagnetic beam to different locations within the eye. An optical path propagates the electromagnetic beam from a light source to the focal point, and also propagates a portion of the electromagnetic beam reflected from the focal point location back along at least a portion of the optical path. The optical path includes an optical element associated with a confocal detection assembly that diverts a portion of the reflected electromagnetic radiation to a sensor. The sensor generates an intensity signal indicative of intensity the electromagnetic beam reflected from the focal point location. The confocal bypass assembly reversibly diverts the electromagnetic beam along a diversion optical path around the optical element.

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: A dynamic random access memory (DRAM) device includes functions configured to aid with operating the DRAM device as part of data caching functions. In response to some write and/or read access commands, the DRAM device is configured to copy a cache line (e.g., dirty cache line) from the main DRAM memory array, place it in a flush buffer, and replace the copied cache line in the main DRAM memory array with a new (e.g., different) cache line of data. In response to conditions and/or events (e.g., explicit command, refresh, write-to-read command sequence, unused data bus bandwidth, full flush buffer, etc.) the DRAM device transmits the cache line from the flush buffer to the controller. The controller may then transmit the cache line to other cache levels.

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.

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: 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.

Abstract: A laser surgery system includes a light source, an eye interface device, a scanning assembly, a confocal detection assembly and preferably a confocal bypass assembly. The light source generates an electromagnetic beam. The scanning assembly scans a focal point of the electromagnetic beam to different locations within the eye. An optical path propagates the electromagnetic beam from a light source to the focal point, and also propagates a portion of the electromagnetic beam reflected from the focal point location back along at least a portion of the optical path. The optical path includes an optical element associated with a confocal detection assembly that diverts a portion of the reflected electromagnetic radiation to a sensor. The sensor generates an intensity signal indicative of intensity the electromagnetic beam reflected from the focal point location. The confocal bypass assembly reversibly diverts the electromagnetic beam along a diversion optical path around the optical element.

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: Embodiments of this disclosure disclose an imaging system, including an eye interface device, a scanning assembly, a beam source, a free-floating mechanism, and a detection assembly. The beam source generates an electromagnetic radiation beam. The detection assembly generates a signal indicative of an intensity of a portion of the electromagnetic radiation beam reflected from the focal point location. A subsequent focal point of the electromagnetic radiation beam may be adjusted per the measured intensity signal. In some embodiments, an intensity signal below a lower threshold value may suggest a depth increase for a subsequent focal point. An intensity signal above an upper threshold value may suggest a depth decrease for a subsequent focal point. And, an intensity signal between the lower and upper thresholds may suggest a depth be maintained for a subsequent focal point. The focal point may be adjusted after each pulse or after a plurality of pulses.
