Firstly, exp[...]texto impreso
Clemente Barreira, Juan Antonio ; Hubert, Guilaume ; Fraire, Juan ; Franco Peláez, Francisco Javier ; Villa, Francesca ; Rey, Solenne ; Baylac, Maud ; Puchner, Helmut ; Mecha, Hortensia ; Velazco, Raoul | IEEE-Inst Electrical Electronics Engineers Inc | 2018-02-01This paper presents a SEU sensitivity characterization at ultra-low bias voltage of three generations of COTS SRAMs manufactured in 130 nm, 90 nm and 65 nm CMOS processes. For this purpose, radiation tests with 14.2 MeV neutrons were performed f[...]texto impreso
Fabero Jiménez, Juan Carlos ; Mecha López, Hortensia ; Franco Peláez, Francisco Javier ; Clemente Barreira, Juan Antonio ; Korkian, Golnaz ; Rey, Solenne ; Cheymol, Benjamin ; Baylac, Maud ; Hubert, Guillaume ; Velazco, Raoul | IEEE-Inst Electrical Electronics Engineers Inc | 2020A sensitivity characterization of a Xilinx Artix-7 FPGA against 14.2 MeV neutrons is presented. The content of the internal SRAMs and flip-flops were downloaded in a PC and compared with a golden version of it. Flipped cells were identified and [...]texto impreso
