An integrated circuit including a memory module having a plurality of memory banks is disclosed. One embodiment provides an even number of at least four memory banks. Each memory bank has a plurality of memory cells. Each two of the memory bank form a memory bank region and being alternately connected to an m-bit data bus. The memory banks are classified into two groups, each group including a memory bank of each memory bank region. The memory module further includes a selection device connected to the memory banks and being responsive to selection bits. The selection device selects one of the two groups of memory banks and a group of i memory cells within the memory banks of the selected group of memory banks to access the selected i memory cells per one stroke via the associated m-bit data buses of the memory groups including the selected memory banks, m being equal to an integer multiple of i.
