An apparatus and method are disclosed for transferring information into an integrated circuit over the power supply pins of the integrated circuit. The apparatus and method are used to load a test program into memory of the computer system and the system is caused to execute the test program to verify proper operation of the computer system. The apparatus and method are implemented by converting the information to be loaded into a serial bit stream, using the serial bit stream to modulate the power supply voltage of the computer system. Inside the RAM device(102), the low power supply levels are sensed by a low power supply detection unit(201)and fed to a serial-to-parallel converter(202) where it is converted back into the original information and stored in storage array(204). A CPU(101)may execute the test program out of RAM(102). |
