摘要:
The present invention has an object of providing a high-speed, low-cost, and user-friendly information processing system that can ensure scalability of memory capacity. The information processing system is configured to include an information processing device, a volatile memory, and a nonvolatile memory. By serially connecting the information processing device, the volatile memory, and the nonvolatile memory and reducing the number of connection signals, processing speed is increased while maintaining the scalability of memory capacity. When transferring data of the nonvolatile memory to the volatile memory, error correction is performed, thereby improving reliability. The information processing system including the plurality of chips is configured as an information-processing system module in which the chips are alternately stacked and arranged, and wired by a ball grid array (BGA) or by bonding between the 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.

In order to implement a memory having a large storage capacity and a reduced data retention current, a non-volatile memory, an SRAM, a DRAM, and a control circuit are modularized into one package. The control circuit conducts assignment of addresses to the SRAM and DRAM, and stores data that must be retained over a long period of time in the SRAM. In the DRAM, a plurality of banks are divided into two sets, and mapped to the same address space, and sets are refreshed alternately. A plurality of chips of them are stacked and disposed, and wired by using the BGA and chip-to-chip bonding.

Efficient and convenient storage systems and methods are presented. In one embodiment a storage system includes a plurality of storage nodes and a master controller. The storage nodes store information. The storage node includes an upstream communication buffer which is locally controlled at the storage node to facilitate resolution of conflicts in upstream communications. The master controller controlls the flow of traffic to the node based upon constraints of the upstream communication buffer. In one embodiment, communication between the master controller and the node has a determined maximum latency. The storage node can be coupled to the master controller in accordance with a chain memory configuration.

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.

A semiconductor device including a large capacity non-volatile memory and at least one random access memory, said the access time of said device being matched to the access time of each random access memory. The semiconductor memory device is comprised of: a non-volatile memory FLASH having a first reading time; a random access memory DRAM having a second reading time which is more than 100 times shorter than the first reading time; a circuit that includes a control circuit connected to both the FLASH and the DRAM and enabled to control accesses to those FLASH and DRAM; and a plurality of I/O terminals connected to the circuit. As a result, FLASH data is transferred to the DRAM before the DRAM is accessed, thereby matching the access time between the FLASH and the DRAM. Data is written back from the DRAM to the FLASH as needed, thereby keeping data matched between the FLASH and the DRAM and storing the data.

A parts aligner is provided with an attraction means 8 orbitally movable in a specific orbit R, and also provided with a posture shift guide 11, a regulating piece 12 and a thickness sorting guide 13 along a specific circumference P corresponding to the specific orbit R in the order of the direction of orbital movement of the attraction means 8. With this structure, only regular parts shifted into a specific posture are guided to an alignment and feed guide 14 and irregular parts are stored in an irregular parts storing part 16.
