writeback
- (Informatique) Copie des données du cache sur la mémoire vive selon les cas.
- When the processor core writes to memory, the cache controller has two alternatives for its write policy. The controller can write to both the cache and main memory, updating the values in both locations; this approach is known as writethrough. Alternatively, the cache controller can write to cache memory and not update main memory, this is known as writeback or copyback. — (ARM System Developer's Guide: Designing and Optimizing System Software, Andrew Sloss, Dominic Symes, Chris Wright, 10 mai 2004)
