Abstract: In one embodiment, a processor includes a core having a fetch unit to fetch instructions, a decode unit to decode the instructions, and one or more execution units to execute the instructions. The core may further include: a first pair of block address range registers to store a start location and an end location of a block range within a non-volatile block storage coupled to the processor; and a block status storage to store an error indicator responsive to an occurrence of an error within the block range during a block operation. Other embodiments are described and claimed.

Abstract: Memory corruption detection technologies are described. A processing system can include a processor core including a register to store an address of a memory corruption detection (MCD) table. The processor core can receive, from an application, a memory store request to store data in a first portion of a contiguous memory block of the memory object of a memory. The memory store request comprises a first pointer indicating a first location of the first portion in the memory block to store the data. The processor core can retrieve, from the MCD table, a write protection indicator that indicates a first protection mode of the first portion. The processor core can send, to the application, a fault message when a fault event associated with the first portion occurs based on the first protection mode of the first portion.
