Publication number: 20170194040Abstract: A memory having stacked memory modules in which heat generated during memory read/write operations can be effectively dissipated, thus avoiding an undesirable localized temperature rise. The storage device is provided with a plurality of stacked memory modules. When a data write request is received, a data processing device that fulfills the role of a memory controller sequentially selects a memory module that is to be a write destination in such a manner that memory modules to which data is written simultaneously are not adjacent to each other, and in a series of write sequences, the memory module to which data is to be written at a subsequent write timing is not adjacent to the memory module to which data is written at a preceding write timing. As a result, the locations of heat generation among the plurality of stacked memory modules are distributed, reducing a rise in temperature.Type: ApplicationFiled: November 11, 2014Publication date: July 6, 2017Applicant: FIXSTARS CORPORATIONInventors: Satoshi Yoneya, Ryoji Tsuchiyama, Masana Murase, Noriyuki Futatsugi

Publication number: 20170003890Abstract: The problem addressed by the present invention is to provide a means for suppressing a drop in overall performance that occurs when data rewriting is concentrated in a specific memory in a data-processing system comprising a plurality of memories, in which a number of possible rewrites is limited. A data-processing system as in one embodiment of the present invention comprises a management device and a plurality of data-processing devices. Each data-processing device comprises a memory, which is a NAND flash memory. Each data-processing device transmits, to management device, status data indicating a number of data rewrites to memory of the host device. Management device allocates data processing to the data-processing device having the smallest number of data rewrites indicated by the received status data.Type: ApplicationFiled: November 11, 2014Publication date: January 5, 2017Applicant: FIXSTARS CORPORATIONInventors: Satoshi Yoneya, Keishi Chikamura

Patent number: 7266615Abstract: Disclosed is a method for interchanging contents information and a system for interchanging contents information. A loop that a receiving side CL1 sends a request signal CL1a carrying position data pd to a sending side SV1 through a communication system NT, the sending side SV1 sends back contents information corresponding thereto as a sending signal SV1a, and the receiving side CL1 displays the signal is repetitively updated and performed at a high frequency by repetitively updating and sending the position data pd at a high frequency. Since the achievable frequency of repetitive updating and performing the loop varies by the combination of receiving side CL1, communication system NT, and sending side SV1, the achievable maximum frequency mxfQ for each loop is determined from a given table or by actual measurement. A standard frequency stfQ which does not exceed the thus determined frequency is set, the processes along the loop are performed at the standard frequency stfQ or a lower frequency.Type: GrantFiled: April 2, 2003Date of Patent: September 4, 2007Assignee: Sony CorporationInventors: Satoshi Yoneya, Yuichi Kojima, deceased, Norikazu Ito

Patent number: 6798972Abstract: There is provided an image reproducing apparatus and an image reproducing method which allow reproducing speed to be shifted instantly when a change of the reproducing speed is requested in a multi-channel AV (Audio Visual) server. When a request to reproduce an image is made, the image reproducing apparatus reads image data of the part corresponding to the requested reproducing speed out of the HDDs to store in a temporary storage section. Then, an image output I/F reads the image data stored in the temporary storage section and structures a reproduced image by using the image data. In this case, a controller section controls a pattern in reading the divisional data by the image output I/F and structures a reproduced image by means of various reproducing speeds by this reading pattern.Type: GrantFiled: March 24, 2000Date of Patent: September 28, 2004Assignee: Sony CorporationInventors: Norikazu Ito, Satoshi Yoneya, Masakazu Yoshimoto, Satoshi Katsuo, Jun Yoshikawa, Shouji Nakamura, Tomohisa Shiga, Masaki Hirose
