The Effects of Alpha Particles on the Sense Amplifier in Memory Devices

The purpose of this paper is to investigate the effects of alpha particles on the memory circuits such as a sense amplifier and bit lines. Sense amplifiers column alpha particle hits have been simulated for a mega bit DRAM using SPICE, a circuit simulation program. The energy of alpha particle and the substrate concentration are found to strongly influence the likehood of soft errors. Our results may be useful for the designing of alpha particle immune sense amplifiers.
