    Abstract

    Ionizing radiation sensor based on the nonvolatile floating gate (FG) C-Flash memory is demonstrated. The sensing is based on measuring the threshold voltage (Vt) shift of the modified C-Flash cell pre-charged by electrons or holes. The accumulated absorbed dose is calculated from the Vt shift of the memory cell after the exposure to radiation. The developed sensor is a candidate for embedding into passive RFID radiation measuring systems. It features ultra-low power operation and does not require power supply during the exposure sessions. The feasibility results for stand-alone sensors and 2kbit test arrays are presented and discussed in view of possible applications.
