To enhance the speed of first access (read access different in word line from the previous access) to a multi-bank memory, multi-bank memory macro structures are used. Data are held in a sense amplifier for every memory bank. When access is hit to the held data, data latched by the sense amplifier are output to thereby enhance the speed of first access to the memory macro structures. Namely, each memory bank is made to function as a sense amplifier cache. To enhance the hit ratio of such a sense amplifier cache more greatly, an access controller self-prefetches the next address (an address to which a predetermined offset has been added) after access to a memory macro structure so that data in the self-prefetched address are preread by a sense amplifier in another memory bank.

An apparatus and a method for implementing an execution configuration for efficiently recording and reproducing data using distributed nodes are provided. When data recording processing is performed for a plurality of distributed nodes connected to a network or when data recorded in the distributed nodes is collected and reproduced, a processing command apparatus sets data for determining for the nodes to determine whether to execute data recording or data reproducing and transmits a data processing request, in which the data for determination and data specifying data to be recorded or reproduced are stored, to the nodes so that the node side can autonomously determine whether to execute data processing based on the data for determination. This configuration eliminates the need for the command apparatus, which issues a processing request, to perform preprocessing such as the selection of a particular node, thus increasing the efficiency of data recording and reproducing processing for distributed nodes.
