Abstract
An integrated circuit chip having a digital memory is provided wherein direct access to at least a portion of the memory is prevented. Contact pads having coupling lines to couple the contact pads to the memory bus are provided. A security code can be programmed into a portion of the memory during wafer probe and test. When the integrated circuit chip is removed from the wafer the coupling lines between the contact pads and the memory bus are destroyed since the coupling lines are made to extend off of the chip.
