The present application is directed to employing intermediary structures for facilitating access to secure memory. A secure driver (SD) may be loaded into the device to reserve a least a section of memory in the device as a secure page cache (SPC). The SPC may protect application data from being accessed by other active applications in the device. Potential race conditions may be avoided through the use of a linear address manager (LAM) that maps linear addresses (LAs) in an application page table (PT) to page slots in the SPC. The SD may also facilitate error handling in the device by reconfiguring VEs that would otherwise be ignored by the OS.
