Abstract
A flash memory system includes a path selector to determine to write to a non-volatile memory, a volatile memory or both the non-volatile memory and the volatile memory when the flash memory system is to write data. A record is stored in the non-volatile memory which is updated the status of the non-volatile memory after each one or more writing operations. When the flash memory system is powered on after a power loss, it could be recovered to a command executed prior to the power loss or to any checkpoint prior to the power loss by using the record.
