Classification: CPC G  H | IPC G  H

Claim 18:
19. A method, comprising:
reading data from a first logical partition of a memory array of a memory device, the data comprising:
user data;
first error correction data corresponding to the user data and calculated by an external controller from the user data; and
second error correction data calculated by an error correction code component of the memory device from the user data;

correcting the user data with the second error correction data;
sending the corrected user data from the error correction code component to a cryptographic component of the memory device;
calculating, via the cryptographic component, a cryptographic measure from the corrected data;
comparing the calculated cryptographic measure to a golden measure stored in the memory array; and
in response to the calculated cryptographic measure not matching the golden measure, replacing the first logical partition with a second logical partition.
