- Dirty Bit: Indicates whether the data in cache and in memory is consistent. If the dirty bit is set to 1, we should flush and write to memory the next time the cache line is evicted.
- Line state: See MSI, MESI slides. Represents the state of the cache line.
- Tag: Identifies the block that stores the line. In other words, the tag is what uniquely identifies the address.
