Abstract
A system for programming integrated circuit (IC) dies formed on a wafer includes a magnetic field transmitter that outputs a digital test program as a magnetic signal. At least one digital magnetic sensor (e.g., Hall effect sensor) is formed with the IC dies on the wafer. The digital magnetic sensor detects and receives the magnetic signal. A processor formed on the wafer converts the magnetic signal to the digital test program and the digital test program is stored in memory on the wafer in association with one of the IC dies. The magnetic field transmitter does not physically contact the dies, but can flood an entire surface of the wafer with the magnetic signal so that all of the IC dies are concurrently programmed with the digital test program.
