摘要:
An object of the present invention is to provide an electronic component using a Cu-based conductive material that can suppress oxidization even in a heat treatment in an oxidizing atmosphere and that can suppress an increase in an electrical resistance. In an electronic component having an electrode or a wiring, a ternary alloy made from three elements consisting of Cu, Al, and Co is used as a Cu-based wiring material that can prevent oxidization of the electrode or the wiring. Specifically, part or the whole of the electrode or the wiring has a chemical composition in which an Al content is 10 at % to 25 at %, a Co content is 5 at % to 20 at %, and the balance is composed of Cu and unavoidable impurities, and the chemical composition represents a ternary alloy in which two phases of a Cu solid solution formed by Al and Co being dissolved into Cu and a CoAl intermetallic compound coexist together.

A read cache and a write cache are made up of two kinds of nonvolatile memories whose characteristics are different. For example, nonvolatile memory whose write endurance is high is assigned to the write cache, nonvolatile memory whose write endurance is low is assigned to the read cache, and the management tables of data in these caches are stored in the nonvolatile memory whose write endurance is high. Alternatively, nonvolatile memory that has a fast write speed but has a slow read speed is adopted for the write cache and nonvolatile memory that has a fast read speed but has a slow write speed is adopted for the read cache.

A memory system including ROM and RAM in which reading and writing are enabled. A memory system includes a non-volatile memory (FLASH), DRAM, a control circuit, and an information processing device. Data in FLASH is transferred to SRAM or DRAM in advance. Data transfer between the non-volatile memory and the DRAM can be performed in the background. The memory system including these plural chips is configured as a memory system module in which each chip is mutually laminated and each chip is wired via a ball grid array (BGA) and bonding wire between the chips. Data in FLASH can be read at the similar speed to that of DRAM by securing a region in which the data in FLASH can be copied in DRAM and transferring the data to DRAM in advance immediately after power is turned on or by a load instruction.

A memory system including a non-volatile memory, a cache memory, a control circuit, and a data processing device is configured. The high speed can be achieved by transferring data in the non-volatile memory to the cache memory to retain the same therein. When the data in the non-volatile memory is transferred to the cache memory, error correction is performed so as to improve the reliability. Since the cache memory and the non-volatile memory can be accessed from the data processing device independently, improvement in usability can be achieved. The memory system including the plurality of chips is configured as a memory system module where respective chips are arranged in a stacked manner and wired by a ball grid array (BGA) and wire bonding between chips.

A memory controller and data processor have their operation mode switched from the page-on mode for high-speed access to a same page to the page-off mode in response to consecutive events of access to different pages, so that the memory access is performed at a high speed and low power consumption.

A laser beam processing machine comprising a chuck table for holding a workpiece, a laser beam application means for applying a pulse laser beam to the workpiece held on the chuck table, and a processing-feed means for processing-feeding the chuck table and the laser beam application means relative to each other, wherein the machine further comprises a feed amount detection means for detecting the processing-feed amount of the chuck table and a control means for controlling the laser beam application means based on a detection signal from the feed amount detection means, and the control means outputs an application signal to the laser beam application means for each predetermined processing-feed amount based on a signal from the feed amount detection means.

A small-diameter front-end portion of a feed rod is allowed to enter into the screw hole of a nut delivered by a nut chute, and the nut is fed to an intended position by the forward movement of the feed rod. When an abnormal nut having a screw hole into which the small-diameter front-end portion cannot be inserted is delivered, the abnormal nut is prevented from being flicked by the feed rod. In order to achieve this, in a standby state, the small-diameter front-end portion of the feed rod enters a nut receiving chamber and is then stopped. On condition that the abnormal nut is received in the nut receiving chamber, if the feed rod moves forward to enter into the standby state, the abnormal nut is slightly pushed out forward from the nut receiving chamber.
摘要:
In an information processor system including a memory device (MEM0), a memory control device (SL0) capable of controlling an operation of the memory device, and a plurality of bus masters (MS0 to MS3) capable of giving access to the memory device through the memory control device, the memory control device includes a control circuit (SDCON) capable of giving a notice of information about a time that a data transfer from the memory device can be started to the bus master related to an access request. The bus master can cause the time information thus given to be a judgment factor as to whether an access request is given to the memory device or not. Consequently, each of the bus masters can avoid the generation of a useless access request and a data transfer to the masters to be accessed can be carried out smoothly.
摘要:
A storage system and method for storing information in memory nodes. The storage or memory nodes include a communication buffer. Flow of information to the storage nodes is controlled based upon constraints on the communication buffer. In one embodiment, communications between a master controller and a storage node have a determined maximum latency.
