摘要： A translation table has entries that each include a share bit and a delta bit, with pointers that point to a memory block that includes reuse bits. When two translation table entries reference identical fragments in a memory block, one of the translation table entries is changed to refer to the same memory block referenced in the other translation table entry, which frees up a memory block. The share bit is set to indicate a translation table entry is sharing its memory block with another translation table entry. In addition, a translation table entry may include a private delta in the form of a pointer that references a memory fragment in the memory block that is not shared with other translation table entries. When a translation table has a private delta, its delta bit is set.
