Abstract
A method for storing encrypted data in a non-volatile memory device, that includes receiving, by a processor, an indication of a power interruption event; disabling, based on the indication, decryption of encrypted data read from a volatile memory module; copying the encrypted data from the volatile memory module to cache; and copying the encrypted data from the cache to the non-volatile memory device.
