Abstract

PURPOSE:To shorten a necessary access time and to improve a processing efficiency by storing collectively directory information corresponding to the node or leaf of the same hierarchy connected to the node of the same high order to the necessary number of said memory blocks. CONSTITUTION:The directory information of the node of the route of a first hierarchy is stored into a first memory block 22 and the directory information of the node of a second hierarchy is stored into a second memory block 22 and the directory information of the node or leaf of a third hierarchy connected to respective nodes of the second hierarchy is stored into respective memory blocks 23-25, etc. Hereinafter, at the time of the low order hierarchy, the same operation is executed. Thus, the number of memory blocks necessary to the reading can be made approximately the same concerning all leaves and uniformly, the access time can be shortened.
