<P>PROBLEM TO BE SOLVED: To provide a memory management device, a memory management method and a program which can prevent plenty of pages having frequent patterns such as zero pages from accumulating in memory without requiring high calculation processing power. <P>SOLUTION: When a pattern of write data is a frequent pattern (YES at ST101) and the write data has already been retained in memory (YES at ST103), then the memory management device sets a common reference on any write data having the frequent pattern. Thereby the device can prevent the plenty of capacity of data having frequent patterns from accumulating in the memory. Thus its available memory increases, and the device can use the memory effectively. <P>COPYRIGHT: (C)2012,JPO&INPIT |
