Information processing device having data field and operation methods of the same

摘要

An information processing device includes a memory array and a controller. The memory array includes a data field that stores file data and a management information field that stores information regarding the data field. The controller controls a writing operation to the memory array. The controller stores a portion of the file data, corresponding to a product of a positive-integer and a predetermined unit block size, in the data field by block units, with reference to the data field information of the management information field.

1. An information processing device, comprising:
a memory array comprising a data field for storing file data and a management information field for storing information regarding the data field, the data field comprising a first data region formed of a plurality of cluster blocks, each cluster block including a predetermined number of clusters and having a predetermined size corresponding to the predetermined number of clusters, and a second data region formed of a plurality of clusters; and a controller for controlling a writing operation to the memory array, the controller being configured to divide the file data into a first portion evenly divided by the predetermined cluster block size and a second portion corresponding to a remainder of the file data, to write the first portion of the file data in the first data region by block unit corresponding to the predetermined cluster block size, and to write the second portion of the file data in the second data region by cluster unit, with reference to the data field information of the management information field.
