ABSTRACT:
A system and method for semiconductor identification chip read out is presented. A user uses a stand-alone handheld device to extract product data, which includes manufacturing process attributes, from a semiconductor device. The semiconductor device couples to the hand held device through a subset of pins, such as a power pin, a ground pin, a clock in pin, and a data out pin. When coupled, the handheld device provides a clock signal to the semiconductor device. In turn, on chip logic within the semiconductor device detects the clock signal and gathers internal product data. Once gathered, the on chip logic provides the product data to the hand held device through the data out pin for a user to view. As a result, the user may track semiconductor devices more efficiently.
