Abstract:
A data storage apparatus includes a NAND flash memory, an external memory and two cores. The external memory includes a first portion and a second portion smaller than the first portion. Each of the cores includes a CPU, an ITCM and a DTCM. The data storage apparatus is switchable between an operative state and hibernation. In the hibernation, the NAND flash memory, the first portion of the external memory, the CPU of the first core, and the CPU, ITCM and DTCM of the second core are shut down while the second portion of the external memory and the ITCM and DTCM of the first core are kept awake.

Claim (Index 7):
The power management method for according to  claim 2 , wherein the hibernation routine comprises the steps:\n using the CPU ( 30 ) of the second core ( 20 ) to receive an FE from the ITCM ( 32 ) of the second core ( 20 ), execute the FE to receive the hibernation request, and provide a DC request; using the CPU ( 30 ) of the second core ( 20 ) to receive the DC from the ITCM ( 32 ) of the second core ( 20 ), execute the DC to write data into the NAND flash memory ( 14 ) from a DC buffer, and provide an FTL write request; using the CPU ( 24 ) of the first core ( 18 ) to receive the FTL from the ITCM ( 26 ) of the first core ( 18 ), execute the FTL to write user data into the NAND flash memory ( 14 ) from a FTL buffer, and execute a callback function for the DC request; using the CPU ( 30 ) of the second core ( 20 ) to execute the DC to invalidate the DC buffer and provide a hibernation request for the FTL; using the CPU ( 24 ) of the first core ( 18 ) to execute the FTL to close User/System/SysMeta spaces, invalidate a GMT cache, and execute a callback function for the DC request; using the FTL to record the power state, a resume entry and context of the CPU ( 24 ) of the first core ( 18 ) and monitor the power state; using the DC callback function to execute a callback function for the FE; and using the FE callback function to monitor the system state and kick off the hibernation.
