Abstract: The disclosed technology provides for a solid state device that adaptively determines, responsive to receipt of a write command, whether or not to partition one or more individual logical blocks of data between multiple pages of a flash storage device.

Abstract: Method and apparatus for managing data in a memory. In accordance with some embodiments, a recovery data set representing a current state of a storage device is stored in a rewritable non-volatile memory responsive to detection of a potentially imminent deactivation of the device. The recovery data set is swapped with a boot data set in said memory responsive to subsequent deactivation of the device. The boot data set is subsequently used to transition the device from a deactivated mode to an operationally ready mode during device reinitialization. The boot data set is thereafter swapped with the recovery data set to return the device to the current state.
