Not too sure about that. Out of touch with flash RAM but several years ago at work we had an EEPROM reprogrammer. Cost a few hundred dollars but the real cost was in the programming we wanted to put on the chip. Assuming flash memory is similar it would be relatively cheap, once you knew how to program the size, to reprogram memory chips.
