Abstract: The present disclosure generally relates to a XTS cache operation during a power down event. Upon detection of power loss, data that is waiting to be encrypted needs to be flushed to the memory device. For any unaligned data or data less than a flash management unit (FMU) size, the data is grouped together and, if necessary, padded to reach the FMU size and then encrypted, merged with other data FMUs, and written to the memory device. Grouping the unaligned data reduces the amount of padding necessary to reach FMU size and also reduces the amount of data to be encrypted. As such, data flushing can be accomplished using the limited amount of remaining power during the power loss event.
