ABSTRACT:
A method is provided for accessing data stored in memory (76). First data appearing at outputs (102) of memory (76) are read during a first reading cycle in a sequence of reading cycles, the first data retrieved from a first location in memory (76) corresponding to a first address. At the end of the first reading cycle, the first address is stepped to produce a second address corresponding to a second location in memory (76). During an idle period following the first reading cycle and prior to a second reading cycle occurring next in the sequence of reading cycles, second data is prefetched from the second location in memory (76) such that the second data appears at the bitlines (102) of memory (76) at the start of the second reading cycle.
