1. An apparatus, comprising: memory; and logic, at least a portion of which is implemented in processing circuitry coupled to the memory, the logic to: determine first and second regions of the memory in which to store first and second portions of system management mode (SMM) information, the first portion of SMM information comprising SMM code and the second portion of SMM information comprising SMM data; insert the SMM code into the first region of the memory and the SMM data into the second region of the memory; and apply a first set of one or more characteristics to the first region of the memory via a first instruction set architecture (ISA) operation and a second set of one or more characteristics to the second region of memory via a second ISA operation, the first set of one or more characteristics comprising an immutable characteristic to prevent modification of the SMM code in the first region of the memory and a no page table accesses permitted characteristic and the second set of one or more characteristic comprising a page table accesses permitted characteristic.
