摘要： A semiconductor memory device includes signal lines, a decoder for decoding an inputted address to output the decoded result to some of the signal lines, a matrixed memory array, a part of which being pre-specified as a compensated area, read out means for reading out data from memory cells in an area specified in accordance with a decode signal on the some signal line, a detector for detecting that the address is related with the compensated area from the decode signal on the some signal lines, the compensated area being pre-related with the some signal lines, and a fixed data outputting circuit for merging predetermined data into a predetermined part of the data read out from the memory cells in accordance with the detection signal to output the merged data. The fixed data outputting circuit is controlled by a control circuit in response to a merge control signal to output the data read out from the memory cells without the merging operation.

摘要： In a computer system having an interface with an I/O bus given disconnect/reconnect functions and a plurality of magnetic disk subsystems connected with the I/O bus, control divides a file at a disk access time with reference to disk management information, file management information and file descriptor translation information to read/write a plurality of such files asynchronously. Thus, high speed file access can be realized by only the plurality of magnetic disk subsystems without requiring any special control hardware. A corresponding relation between subfiles in a virtual directory and the application request file can be taken to construct the directory, thus making the divided storage transparent to the application.
摘要翻译：在具有与断开/重新连接功能的I / O总线接口以及与I / O总线连接的多个磁盘子系统的计算机系统中，控制器参考磁盘管理信息来分割磁盘访问时间的文件，文件管理信息和文件描述符翻译信息，以异步地读/写多个这样的文件。因此，只有多个磁盘子系统可以实现高速文件访问，而不需要任何特殊的控制硬件。可以采用虚拟目录中的子文件与应用程序请求文件之间的对应关系来构造目录，从而使分割的存储对应用程序透明。
