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. 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, wherein the private delta references previously-stored content. When a translation table has a private delta, its delta bit is set. The private delta is generated by analyzing a data buffer for content that is similar to previously-stored content.
