The problem of radiation hardness in memory bit cells is very well renowned and explored. The need for solutions compliant with standard electronics processes is however more and more important both for medical applications and High Energy Physics experiments.
In the world of radiation hard Non-Volatile Memories, the topic of reliability has always been a primary focus. Nevertheless, considering the cost of special processes for innovative bit cells such as MRAMs and Phase Change Bit Cells, inherently more robust, the investigation and innovation of charge-based cells is still of primary importance. This poster is to present the measurement setup for Sidewall Spacer (SwSpc) Memory Bit Cells, that has the advantage to sustain live measurements during irradiation, including PROGRAM and ERASE operations, ID / VG and Vth / TPROG curves on the cells themselves, and has sub-10nA accuracy with 2m cables to fit most X-ray tube irradiator setups.
