According to exemplary embodiments, a computer program product, system, and method for prefetching in memory include determining a missed access request for a first line in a first cache level and accessing an entry in a prefetch table, wherein the entry corresponds to a memory block, wherein the entry includes segments of the memory block. Further, the embodiment includes determining a demand segment of the segments in the entry, the demand segment corresponding to a segment of the memory block that includes the first line, reading a first field in the demand segment to determine if a second line in the demand segment is spatially related with respect to accesses of the demand segment and reading a second field in the demand segment to determine if a second segment in the entry is temporally related to the demand segment. |
