A data array 20 to be stored is first divided into a plurality of blocks 21. Each block 21 is further sub-divided into a set of sub-blocks 22, and a set of data for each sub-block 22 is then stored in one or more body blocks 25. A header data block 23 is stored for each block 21 at a predictable memory address within a header buffer 24. Each header data block contains pointer data indicating the position within a body block 25 where the data for the sub-blocks for the block 21 that that header data block 23 relates to is stored, and data indicating the size of the stored data for each respective sub-block 22.
