Specification

prevents the host from sending in further address/instructions/data that may be corrupted. During power disturbance,
the host is likely experiencing a voltage drop, so the transmission integrity cannot be guaranteed. Second, it stops the
information sending to the Flash. This prevents the controller from corrupting the address/data being transmitted to the
Flash, and corrupting the Flash contents inadvertently.
Further more, Advanced Power Shield cut off the connection between host power and turn off the controller to
reserve most of the energy for NAND Flash to complete programming. Due to MLC structure, an interrupted
programming may damage a paired page which cause the previous written data lost.
Note:Transcend does not guarantee that data can be protected by Power Shield/ Advanced Power Shield under all
conditions.
