PROBLEM TO BE SOLVED: To provide a method for decreasing waiting time for a refreshing action in a dynamic memory. SOLUTION: This refreshing method of a dynamic memory for storing variables related to calculation processing executed by a processor, comprises a planning step 10 of including establishment of order and timing of the calculation processing, a step 13 of estimating holding time peculiar to each variable, a step 14 of predicting at least one moment at which each variable must be refreshed, a disposing step 15 for disposing the variables in the memory, and a refresh acting step 16 of refreshing the variable at the moment defined during the predicting step. This inventions enables to decrease the waiting time and the amount of current consumption in related to the refresh action, and is particularly advantageous in a system wherein real-time restriction is important, for example, a video data processing system.
