DATA REPRODUCING DEVICE, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a data reproducing device of lower electric power by using a refresh-control circuit in which a DRAM can perform a required hold operation with low electric power. SOLUTION: In a DRAM refresh-control circuit, a write address and a read- out address outputted from a DRAM address generating section are inputted to constitute FIFO for data. When it is determined that the value of a refresh- counter is of a higher order than a write address and is of a lower order than a read-out address, a stop signal is issued to a refresh-executing section to stop needless refresh-operation.
