EVICTION OF A CACHE LINE BASED ON A MODIFICATION OF A SECTOR OF THE CACHE LINE

Abstract:

An indication to perform an eviction operation on a cache line in a cache can be received. A determination can be made as to whether at least one sector of the cache line is associated with invalid data. In response to determining that at least one sector of the cache line is associated with invalid data, a read operation can be performed to retrieve valid data associated with the at least one sector. The at least one sector of the cache line that is associated with the invalid data can be modified based on the valid data. Furthermore, the eviction operation can be performed on the cache line with the modified at least one sector.
