Abstract
A data preservation system for flash memory systems with a host system, the flash memory system receiving a host system power supply and energizing an auxiliary energy store therewith and communicating with the host system via an interface bus, wherein, upon loss of the host system power supply, the flash memory system actively isolates the connection to the host system power supply and isolates the interface bus and employs the supplemental energy store to continue write operations to flash memory.
