Abstract: The memory card includes a non-volatile memory, an internal memory, a bus converter, and a media controller. The non-volatile memory is rewritable. The internal memory is configured to divide data transferred from a host into M (M is an integer of 2 or more) segments each of which including N (N is a natural number) times a minimum transfer unit of the non-volatile memory as a unit to record. The bus converter is configured to output 1/M of the minimum transfer unit of data in parallel from each of the M segments recorded in the internal memory. The media controller is configured to integrate 1/M of data belonging to each of different segments input in parallel from the bus converter as one minimum transfer unit of data to record in the non-volatile memory.

Abstract: A recording device includes a plurality of storage modules and a recording controller. With respect to a writing request, the recording controller generates parity data and writes data in the respective plurality of modules by dividing the data. When an error is detected with respect to a reading request, data of the error is restored from data and the parity data read from other recording modules. With respect to an initialization request of the storage module, the storage module to be initialized is specified from the plurality of storage modules, and an address conversion table is initialized. Moreover, identification information for identifying the initialized storage module is held. With respect to a request for cancelling the table initialization request of the storage module, reading of data from the storage module corresponding to the held identification information is processed as an error.

Abstract translation: 记录装置包括多个存储模块和记录控制器。 对于写入请求，记录控制器产生奇偶校验数据，并通过划分数据将数据写入相应的多个模块中。 当相对于读取请求检测到错误时，从数据和从其他记录模块读取的奇偶校验数据恢复错误的数据。 关于存储模块的初始化请求，从多个存储模块指定要初始化的存储模块，并初始化地址转换表。 此外，保持用于识别初始化的存储模块的识别信息。 关于取消存储模块的表初始化请求的请求，对与保持的标识信息相对应的来自存储模块的数据的读取被处理为错误。
