Abstract
A tag check performed for a memory access operation comprises determining whether an address tag associated with a target address of the access corresponds to a guard tag stored in the memory system associated with a memory system location to be accessed. A given tag check architecturally required for a tag-checked load operation can be skipped when a number of tag-check-skip conditions are satisfied, including at least: that there is an older tag-checked store operation awaiting a pending tag check, for which a guard tag checked in the pending tag check is associated with a same block of one or more memory system locations as a guard tag to be checked in the given tag check; and that the address tag for the tag-checked load operation is the same as the address tag for the older tag-checked store operation.
