Abstract:
Systems and methods are described herein for dynamic random-access memory (DRAM) memory devices. In some aspects, a memory device may be constructed in a vertical orientation such that the data-lines run perpendicular to the surface of the substrate and an arbitrary number of layers may be constructed on an area, with at least some of the layers comprising an arbitrarily high density of cells. The memory device may utilize conventional capacitor cells with a refresh function, and the other usual features of activation, sensing, write-back, and selection which are common to Dennard-cell 1T1C DRAM. In some aspects, the cells may use ferroelectric capacitor dielectric resulting in devices which hold charge indefinitely without refresh, but in most other respects operate similarly to the conventional cells.
Abstract:
Systems and methods are described herein for dynamic random access memory (DRAM) devices. In one aspect, a plurality of DRAM cells forms a stacked structure. Individual DRAM cells may include a substantially planar capacitive element formed of two substantially planar electrodes separated by an insulating layer. Individual DRAM cells may also include a transistor in communication with and substantially planar to the capacitive element, and a word line, which activates the access gate of the transistor when a voltage is applied to the access gate, formed proximate to and substantially parallel with the capacitive element. Individual DRAM cells may share at least one data line, oriented in a vertical direction relative to the stacked structure, that is in communication with capacitive elements through the access gate of individual DRAM cells and is operable to store and access charge stored in individual capacitive elements of individual DRAM cells.
Abstract:
Systems and methods are described herein for electron-beam lithography. In some aspects, a photo electron emitter and channel array assembly (PEECAA) may include a photo-electron emitting cathode having a uniform planar surface and an array of beam channels proximate to the cathode. In some cases, at least one of the cathode or the array of beam channels is removable from the PEECAA. The array of beam channels may include a grid of apertures, a plurality of beam channels, and a shared lens array including a plurality of lenses proximate to an exit of the plurality of beam channels. Individual apertures of the grid of apertures align with individual beam channels to allow electrons from the cathode to pass through the array of beam channels and the shared lens array to form a pixelated pattern, such that, upon exposure to the target, the pixelated pattern is permanently formed on the target.
Abstract:
One or more pellicles protect a cathode, the pellicles comprised of a thin layer of material that allows electrons to pass while preventing contamination of the cathode from elements originating beyond the pellicle or contamination of an outside apparatus from elements originating on or near the cathode. The pellicle can be supported by an insulator, the insulator in turn supported by a deflecting layer. The pellicle can be maintained at a positive voltage relative to the cathode, such that a voltage gradient is created between the cathode and the pellicle that accelerates electrons emitted by the cathode away from the cathode. The pellicle is located at an appropriate distance from the cathode to allow electron transmission matching the energy of the electrons at that distance.
Abstract:
A method of coating substrate monoliths is disclosed. The method comprises locating a containment means on top of the first end face of the monolith; and dosing a predetermined quantity of washcoat composition comprising a liquid phase, at least one polysaccharide rheology modifier and at least one of (i) a suspension of metal oxide particles into the containment means; and (ii) at least one metal salt solute in the liquid phase. The locating step may occur before or after the dosing step. Pressure is applied to the washcoat composition to generate shear stress and to transfer an entirety of washcoat composition into the channels of the monolith by plug flow. Substantially all of the predetermined quantity is retained within the monolith. The part-coated monolith is then rotated so that the second end face is located at the top, and the first three steps are repeated without drying the part-coated monolith.
Abstract:
Management of communication operations of wireless devices is provided. A traffic-control parameter is generated, for example at a base station, indicative of desired aspects of communication operations of the wireless devices. The one or more traffic-control parameters may comprise a delay parameter, such as a maximum value for generating random backoff times, and/or a connection-time parameter, indicative of the maximum length of time a wireless device can hold a connection. A bit sequence indicative of the one or more traffic-control parameters is generated and communicated to the wireless devices. A wireless device determines the traffic-control parameter based on the communicated bit sequence and adapts its operation based thereon.
Abstract:
Methods and apparatus for use in communicating messages from a communication device are described. The device receives, via its user interface, an input request for creating a new message. The device also receives, via its user interface, one or more input requests for selecting one or more message recipient identifiers for the new message. In response to receiving the one or more input requests, the device identifies whether a stored conversation thread is associated with conversation participant identifiers that match the conversation participant identifiers for the new message. If so, the device displays the identified conversation thread together with a message body input field of the new message, prior to entry of message body contents in the message body input field. The device then receives, via the user interface, the message body contents in the message body input field, and causes the new message to be transmitted to one or more communication devices identified by the one or more message recipient identifiers.
Abstract:
A device, system and method are provided for presenting message threads in a device display where messages may have a persistent or intermediate status. A list of message threads is displayed, collated according to a given message thread attribute, is displayed. When a new message is detected belonging to one of the message threads, if the message has a persistent status it is added to the message thread and the collating message thread attribute for that thread is updated. If the message has an intermediate status, it may be added to the message thread but the collating message thread attribute for that message is deferred until the intermediate status is changed to a persistent status. The collated list of message threads is then updated. By deferring updates to the collating message thread attribute when a message has an intermediate status, disruption to the order of the collated list is mitigated.
