description	Storage circuitry comprises an array of storage locations arranged in rows and columns, a row buffer comprising a plurality of entries each to store information from a storage location at a corresponding column of an active row of the array, and comparison circuitry responsive to a tag-matching command specifying a tag value to compare the tag value with information stored in each of a subset of two or more entries of the row buffer. The comparison circuitry identifies which of the subset of entries, if any, is a matching entry storing information matching the tag value. This allows memory technologies such as DRAM to be used more efficiently as a set-associative cache.
