PROBLEM TO BE SOLVED: To provide a memory control device which is improved in a processing speed by giving a temporal limitation to the switching operation of a bank in a buffer when writing the data given from a CPU in a memory. SOLUTION: When the bank with data written thereon comes into a memory full state in the buffer 2 or there is no data input till a predetermined time passes after the data is written in this bank, a buffer control part 3 makes readable a writing bank and also makes a next bank for use in writing. When all the data stored in the reading bank is read out in the buffer 2, the buffer control part 3 makes writable the reading bank and also makes a next bank for use in reading.
