INFORMATION PROCESSING DEVICE AND METHOD EXECUTED BY AN INFORMATION PROCESSING DEVICE

An information processing device includes a first memory and a processor configured to receive first data from the second memory, receive second data from the third memory, store the first data and the second data in the first memory, specify a first latency of the second memory and a second latency of the third memory, specify a first access frequency to the second memory, and a second access frequency to the third memory, select one of the first data and the second data based on first value, a second value, a first data volume of the first data, and a second data volume of the second data, the first value being obtained by multiplying the first latency and the first access frequency, and the second value being obtained by multiplying the second latency and the second access frequency, and delete at least a part of data.
