Updated (RevA) modules use a very tiny custom chip labeled 5A32 for NVRAM storage.

Note the circle in this image shows a 10k resistor from pin 5 WP to GND, which the ST M45PE10 datasheet indicates will write-protect the first 64K. To disable this protection according to the SPI datasheet, remove the resistor and solder pin 5 to pin 6 VCC.
