Abstract: Methods, systems, and devices for shared decoder architecture for three-dimensional memory arrays are described. A memory device may include pillars coupled to an access line using two transistors positioned between the pillar and the access line. The gates of the two transistors may be coupled with respective gate lines coupled with circuitry configured to bias the gate line as part of an access operation for a memory cell coupled with the pillar. In some cases, the circuitry may be positioned between tiles of the memory device, at an end of one or more tiles of the memory device, between word line combs of a tile of the memory device, or a combination thereof.

Abstract: Systems, methods, and apparatus for a memory device. In one approach, a memory device selectively enters a streaming mode when accessing memory cells in a memory array. A controller determines for new read operations whether memory cells will be accessed in a streaming mode or in a random mode. First memory cells addressed using a wordline are read by the controller. The wordline is charged to an initial voltage for reading the first memory cells. When in the streaming mode, instead of discharging the wordline after reading the first memory cells, as is done for a random mode, the controller keeps a minimum bias on the wordline and returns the wordline again to the initial voltage for performing a next read operation to read second memory cells. This saves memory device power.

Abstract: Methods, systems, and devices for parallel access in a memory array are described. A set of memory cells of a memory device may be associated with an array of conductive structures, where such structures may be coupled using a set of transistors or other switching components that are activated by a first driver. The set of memory cells may be divided into two or more subsets of memory cells, where each subset may be associated with a respective second driver for driving access currents through memory cells of the subset. Two or more of such second drivers may operate concurrently, which may support distributing current or distributing associated circuit structures across a different footprint of the memory device than other different implementations with a single such second driver.

Abstract: A method for providing motor vehicle wheels made of composite material based on carbon fiber includes the steps of dividing each wheel into a plurality of portions having small dimensions; providing a a first portion with the terminal edges designed to mate with corresponding edges of a respective second portion; mating the portions, arranging them subsequently within a respective mold whose shape and dimensions are conjugate with respect to those of the wheel to be manufactured; and bringing the mold and its contents to a predefined temperature. The method further includes injecting into the mold a resin in the liquid state, the resin being injected at high pressure and high temperature, forming the matrix of the composite that constitutes the wheel; maintaining the pressure and temperature of the mold within predefined ranges for a time interval that is required for the at least partial cross-linking of the resin; and extracting the wheel from the mold.

Abstract: A wheel for supporting tires for vehicles which is made of composite material based on carbon fiber, which includes an insert which is made of metallic material at its central region configured to be fixed to the hub of the respective vehicle. The insert is coupled between external contoured laminated shells made of composite material, with the interposition of at least one interface film having a thickness that can vary between 0.05 mm and 1.0 mm. The interface film is made of a material preferably chosen from among epoxy polymers, polyurethane polymers, acrylic polymers, silicone polymers, polyamide polymers, glass fibers, and combinations thereof.
