Hello Qiaopeng,
Thank you for contacting Cypress Semiconductor
The meaning of the "706FF309 C C05 Spansion" are as follows :
"7" = 2017 production year
"06" = Workweek tf when the device was packaged within 2017 production year
"F" = Package Assembly Location (Japan)
"F" = Mark and Pack Location (Japan)
"306" = 306th wafer lot sequence within the workweek 06
"C" = For Cypress Internal Tracking Purposes only; Transparent to the end user.
"05" = 2005 is the year the circuitry was Copyrighted
"Spansion" = the S29GL128P10TFI01 was originally design and manufactured by Spansion.
Cypress acquired Spansion in March, 2015.
Hope this helps...
Best regards,
Albert

Hello Albert,
Thank you very much for your wonderful answer, but I have another questions to ask.
Sum up. Faulty flash chip surface label are S29GL128P10TF101 706FF309C @05 SPANSION and S29GL128P10TF101
722FF163C @05 SPANSION, and the total number is 18pcs. Have you ever received any feedback about the problems in these two batches before? Or is there a problem with these two batches in the production process?
Below picture one is the power-on waveform of VIO and VCC. Below picture two is the power-down waveform of VIO and VCC. VCC and VIO are connected together. The voltage amplitude is 3.3V. Thank you !
Best regards,
