PROBLEM TO BE SOLVED: To variably set a data size of continuous access from a cache to a main memory.SOLUTION: A memory device includes: a write control circuit which when storing a single line in a data array in accordance with a cache fill request in the single line, sets corresponding management data of a management data array to a first state, and when storing a plurality of continuous lines in the data array in accordance with a cache fill request in the plurality of continuous lines, sets the corresponding management data of the management data array to a second state; and an access control circuit which when the corresponding management data of the management data array indicates the first state in write back, generates a request for writing cache data to be ejected as a single line, and when the corresponding management data of the management data array indicates the second state, generates a request for writing cache data of the data array to be integrated with the cache data to be ejected and the cache data to be ejected as a plurality of continuous lines. |
