Abstract
A cache within a computer system receives a partial write request and identifies a cache hit of a cache line. The cache line corresponds to the partial write request and includes existing data. In turn, the cache receives partial write data and merges the partial write data with the existing data into the cache line. In one embodiment, the existing data is 'modified' or 'dirty.' In another embodiment, the existing data is “shared.” In this embodiment, the cache changes the state of the cache line to indicate the storing of the partial write data into the cache line.
