  • Patent number: 11837271
    Abstract: A memory control apparatus controls access to a DRAM having a plurality of banks. The apparatus comprises a first generating unit configured to generate an access command in accordance with an access request for the DRAM and store the access command in a buffer; a second generating unit configured to generate a bank-designated refresh request for the DRAM; and an issuing unit configured to issue a DRAM command to the DRAM based on an access command stored in the buffer and a refresh request generated by the second generating unit. The second generating unit determines a bank for which the refresh request is generated, based on an access time for each bank of the DRAM by not less than one access command stored in the buffer.
