  • Abstract
    A stable chip-ID generating scheme using random failure bits in an SRAM array is proposed. Combining with a new screening test before shipping products, we realize high-tolerance against variability of operating condition. Measured data confirm that the stability and average of Hamming distance of 128 bit chip-ID achieve 100% and 63.7, respectively. The chip-ID generating time becomes less than 10us at 200 MHz operation.
