摘要：
Aspects of the invention relate to a programmable heavy-ion sensing device for accelerated DRAM soft error detection. Design of a DRAM-based alpha particle sensing apparatus is preferred to be used as an accelerated on-chip SER test vehicle. The sensing apparatus is provided with programmable sensing margin, refresh rate, and supply voltage to achieve various degree of SER sensitivity. In addition, a dual-mode DRAM array is proposed so that at least a portion of the array can be used to monitor high-energy particle activities during soft-error detection (SED) mode.
