    • Provided are a ceramic-fine-particle producing process making it possible to produce, with ease, ceramic fine particles which have a spherical shape close to a complete round and an excellent mono-dispersibility, and are made only of a solid component of a simple ceramic material without making a fine channel structure complicated, and an apparatus used therein for producing ceramic fine particles. The process includes the step (S100) of feeding a dispersion phase made of an aqueous liquid containing a gelling agent to act upon cooling and a ceramic material into a continuous phase made of an oily liquid containing a surfactant, thereby producing fine droplets; the step (S110) of collecting and cooling the produced fine droplets; the step (S120) of washing the cooled fine droplets; the step (S130) of drying the washed fine droplets; and the step (S140) of firing the dried fine droplets.

    • A memory system permitting a number of alternative memory blocks to be made ready in order to extend the rewritable life and thereby contributing to enhanced reliability of information storage is to be provided. The memory system is provided with a nonvolatile memory having a plurality of data blocks in predetermined physical address units and a controller for controlling the nonvolatile memory in response to an access request from outside. Each of the data blocks has areas for holding a rewrite count and error check information regarding each data area. The controller, in a read operation on the nonvolatile memory, checks for any error in the area subject to the read according to error check information and, when there is any error, if the rewrite count is greater than a predetermined value, will replace the pertinent data block with another data block or if it is not greater, correct data in the data block pertaining to the error.

    • The reliability of data is significantly increased without considerably increasing costs by performing minor data corrections within an information storage device and performing major error corrections in an information processing device. When a request to transfer user data for reading is issued from an information processing device, a control circuit transfers the user data and management data to an error detection circuit, which checks the user data for errors. If the user data contains no error, the control circuit notifies the information processing device that the user data can be transferred, and transfers it to the information processing device. If the user data contains errors, an X count error position and correction data calculation circuit uses the user data and the management data to calculate correction locations and correction data, and judges whether the correction locations are correctable. If uncorrectable (there are more correction locations than X locations), the control circuit notifies the information processing device that the user data is uncorrectable, and then transfers the user data and the management data to the information processing device.
    • 通过在信息存储设备内进行小数据校正并且在信息处理设备中执行主要错误校正,数据的可靠性显着增加,而不会显着增加成本。 当从信息处理装置发出用于传送用于读取的用户数据的请求时,控制电路将用户数据和管理数据传送到检错用户数据的错误检测电路。 如果用户数据不包含错误,则控制电路通知信息处理装置可以传送用户数据,并将其传送到信息处理装置。 如果用户数据包含错误,X计数错误位置和校正数据计算电路使用用户数据和管理数据来计算校正位置和校正数据,并且判断校正位置是否可校正。 如果不可校正(比X位置更多的校正位置),则控制电路向信息处理设备通知用户数据是不可校正的,然后将用户数据和管理数据传送到信息处理设备。
