Abstract: A processing device sets a first flag that indicates whether a first critical security parameter (CSP) file exists. The first CSP file includes a first set of CSPs for a memory device. The processing device sets a second flag that indicates whether the first CSP file is valid. The processing device sets a third flag that indicates whether a second CSP file exists. The second CSP file includes a second set of CSPs for the memory device. The processing device sets a fourth flag that indicates whether the second critical security parameter file is valid. The processing device selects one of the first or second CSP file as an active CSP file based on an evaluation of the first, second, third, and fourth flags.

Abstract: A command to perform a data operation at a memory device is received. The command includes an encryption key tag. A first key table is accessed from local memory. The first key table includes a first set of key entries corresponding to a first set of encryption keys. The first key table is searched to determine whether it includes an entry corresponding to the encryption key tag. Based on determining the first key table does not include an entry corresponding to the tag, a second key table is accessed from RAM. The second key table includes a second set of key entries corresponding to a second set of encryption keys. A key entry corresponding to the encryption key tag is identified from the second key table. The key entry includes an encryption key corresponding to the encryption key tag. The command is processed using the encryption key.
