  • Publication number: 20120066432
    Abstract: Provided is a user-friendly information processing system which is capable of maintaining latency within a fixed range and ensuring the expandability of a memory capacity at high speed and low cost. The information processing system, including an information processing device, a volatile memory, and nonvolatile memories, is configured. The information processing device, the volatile memory, and the nonvolatile memories are connected in series with one another to reduce the number of connection signals, thereby realizing speeding-up while maintaining the expandability of the memory capacity. The information processing device manages response time zones and time zones where responses overlap one another, and performs a correction operation on the latency, thereby realizing fast data transfer while maintaining the latency within the fixed range. The information processing device performs an error correction to improve the reliability when transferring the data of the nonvolatile memories to the volatile memory.

  • Publication number: 20120054421
    Abstract: 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.

  • Publication number: 20120030403
    Abstract: 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.

  • Publication number: 20110258373
    Abstract: 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.

  • Publication number: 20110145500
    Abstract: A high-speed, low-cost data processing system capable of ensuring expandability of memory capacity and having excellent usability while keeping constant latency is provided. The data processing system is configured to include a data processing device, a volatile memory, and a non-volatile memory. As the data processing device, the volatile memory, and the non-volatile memory are connected in series and the number of connection signals are reduced, the speed is increased while keeping expandability of memory capacity. The data processing device measures latency and performs a latency correcting operation to keep the latency constant. When data in the non-volatile memory is transferred to the volatile memory, error correction is performed to improve reliability.

  • Publication number: 20110078351
    Abstract: In an information processor system including a memory device (MEMO), 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.

  • Publication number: 20110078366
    Abstract: 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.

  • Patent number: 7896194
    Abstract: 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.

  • Patent number: 7830730
    Abstract: A memory module fast in random accesses, large in capacity, and low in fabricating cost. And the memory module can assure high security. The memory module consists of a flash memory, a dynamic random access memory, and a control circuit. The control circuit enables data transfer between the flash memory and the dynamic random access memory only with a read operation for a specific address in the memory module. When reading data from the memory module, the control circuit refreshes the dynamic random access memory. Thus the present invention can realize a large capacity and low cost memory module capable of reading data fast reading and assuring high security.
