If You Buy A Sim Card On The Street... You Can Hack It!


Recommended Posts

Any given memory device has a controler circuit. In many cases it is cheaper to use a microprocessor/microcontroller than developing a new one. E.g. An 8 bit AVR costs in Sweden 1-2 USD while developing an ASIC costs much more.

Often the controler code is burned into a ROM which can be read but not changed. I still maintain that memory circuits can't be used run malevolent cide. They can only be used to store code which is executed on the computer they are attached to.


Most use FLASH memory to store the code. That way the firmware can be updated.
