Zusammenfassung:Technologies for memory management with memory protection extension include a computing device having a processor with one or more protection extensions. The processor may load a logical address including a segment base, effective limit, and effective address and generate a linear address as a function of the logical address with the effective limit as a mask. The processor may switch to a new task described by a task state segment extension. The task state extension may specify a low-latency segmentation mode. The processor may prohibit access to a descriptor in a local descriptor table with a descriptor privilege level lower than the current privilege level of the processor. The computing device may load a secure enclave using secure enclave support of the processor. The secure enclave may load an unsandbox and a sandboxed application in a user privilege level of the processor. Other embodiments are described and claimed.
