A computer virtual memory system having a translation lookaside buffer (TLB) in which the result of a dynamic address translation system is stored when in a normal mode or when a non-privileged instruction is executed, but the result is not stored when in a privileged mode or when a privileged instruction is executed, such as a storage key operation. The storage does not occur even though the effective address of the privileged instruction is translated into a physical address.
