MEMORY DEVICE DATA SECURITY BASED ON CONTENT-ADDRESSABLE MEMORY ARCHITECTURE

Abstract:

An access request is received. The access request comprises a physical page address corresponding to a primary memory block of a memory device, an input security key, and a logical page address corresponding to the physical page address. The input security key is provided as input to a (CAM) block that stores a plurality of security keys to verify that the input security key matches a stored security key. A location of the stored security key is checked to verify that it corresponds to the logical page address included in the access request based a predetermined mapping. Based on verifying that the stored security key corresponds to the logical page address included in the access request, the physical page address corresponding to the primary memory block is accessed.
