A memory control device for controlling an access from a processing unit to a cache memory, the memory control device includes: an address estimation circuit for receiving a first read address of the cache memory from the processing unit and estimating a second read address on the basis of the first read address; an access start detection circuit for detecting an access start of accessing cache memory at the first read address and outputting an access start signal; a data control circuit for receiving read data from the cache memory and for outputting the read data to the processing unit; and a clock control circuit for controlling a read clock to be output to the processing unit in response to the access start signal, the processing unit receiving the read data from the data control circuit with the read clock.
