Please refer datasheet for more details about Fast read operation. Support for fast read operation is added to make our F-RAM device compatible with serial flash devices, so that you can use the same software. Please see more details on page 8 of datasheet, http://www.cypress.com/file/175731/download .
CY15B102Q is an F-RAM device (not nvSRAM), and it does not need an external capacitor. AN64574 is not applicable for F-RAMs, it talks about nvSRAMs. Connection diagram for CY15B102Q will be same as figure 2 in AN64574.
Thanks and Regards,
