Claim 15:
16. The data cache method of claim 12, wherein the comparator circuit further comprising a first comparator circuit, a second comparator circuit and a third comparator circuit, the method further comprises:
comparing, by the first comparator circuit, the target hash value generated by the compression circuit to the hash value in virtual tag array to determine whether the target hash value hits one way of a set of memory units;
obtaining, by the second comparator circuit, the higher part VA[H] of the virtual address generated by the first AGC and determines whether the higher part VA[H] hits one way of the set of memory units;
when the higher part VA[H] of the virtual address hits one way of the set of memory units, obtaining, by the second comparator circuit, the physical address PA corresponding to the higher part VA[H], and transmit the physical address PA to the third comparator circuit; and
determining, by the third comparator circuit, whether the higher part PA[H] of the physical address PA hits one way of the set of memory units.
