Abstract
Systems, methods, and apparatuses relating to circuitry to implement individually revocable capabilities for enforcing temporal memory safety are described. In one embodiment, a hardware processor comprises an execution unit to execute an instruction to request access to a block of memory through a pointer to the block of memory, and a memory controller circuit to allow access to the block of memory when an allocated object tag in the pointer is validated with an allocated object tag in an entry of a capability table in memory that is indexed by an index value in the pointer, wherein the memory controller circuit is to clear the allocated object tag in the capability table when a corresponding object is deallocated.
