Abstract: A method for DRAM protection comprises allocating address spaces respectively for a first and second common region, a first and second secure region; detecting whether common data has an address within the address spaces for the first secure region; outputting a digital signal remapping an address of the common data to the address space for the second common region if yes; detecting whether secure data has an address within the address spaces for the first common region; outputting a digital signal indicating remapping an address of the secure data to the address space for the second secure region if yes. Alternatively, the method further comprises generating a random key; an updated written data by permuting orders of bits of an original DRAM written data; generating an encrypted data by performing a function on the updated written data with the generated random key; and dynamically updating the generated random key.

Abstract: A one-time programmable (OTP) memory device includes a memory array. The memory array includes: a data storage section for storing application data; a verification information section including at least one verification information unit, wherein each verification information unit includes a verification address region for storing verification address information associated with an address of a subject region in the data storage section, and a reference verification data region for storing one or more reference verification data, and wherein each reference verification data is calculated through reference verification calculation on the application data stored in the subject region using a predetermined verification algorithm.
