Abstract
There is provided an apparatus, system, chip-containing product, method, and storage medium. The apparatus comprises memory access circuitry responsive to one or more types of memory access request, to retrieve specified data items from memory. The apparatus is also provided with local storage circuitry configured to store at least some of the retrieved data items. The local storage circuitry is N-way associative, and N is greater than 1. The apparatus is also provided with control circuitry responsive to an indication that an access request signalled to the local storage circuitry relating to an accessed data item corresponds to a predefined type of memory access request, to implement a restrictive access policy in relation to the accessed data item in the local storage circuitry. The restrictive access policy excludes at least one step of accessing an excluded subset of ways of the local storage circuitry.
