Abstract
A memory access determination circuit includes a counter that switches between a first reference value and a second reference value in accordance with a control signal to generate a count value based on the first reference value or the second reference value. A controller performs a cache determination based on an address that corresponds to the count value and outputs the control signal in accordance with the cache determination. A changing unit changes the second reference value in accordance with the cache determination.
