INTERFACE STM32 TO SRAM USING GPIO PINS

Hi all,
       We are trying to interface a 4M  SRAM (IS62WV25616ALL) to STM32F407IGT6 through GPIO Pins of the controller. We are able to write data sucessfully into the SRAM but we are facing difficulty in READING the same data from the same memory location.
We are not able to figure out where the problem lies (either with the Timing of the SRAM which operates at 70ns or the timing of the GPIO pins of the controller (it operates at 5ns/pin)).... kindly let us know if you have any idea.

Thanks in advance>>>.
