A method is described for controlling data transfer operations between a memory having a plurality of addressable pages and a device operable to write data to and read data from the memory. An address is stored that corresponds with an open page in the memory. A read or write request is received from the device, together with an address corresponding with the requested page from or to which the read or write is to be performed. The requested page address is compared with the stored open page address to determine whether the requested page is already open. The appropriate sequence of memory operations is then initiated to effect the requested read or write data transfer. If a read request, the requested memory page is left open after completion of data transfer operations. If a write request, the requested memory page is closed and precharged following completion of the data transfer operations.
