研究了闪存电路系统中高压电路的总剂量辐射效应(TID)。通过对内部高压电荷泵电路和高压负载电路的TID辐射效应测试研究,表明辐照后高压通路相关的存储阵列及高压晶体管漏电将造成电荷泵电路的负载电流过载失效,最终导致闪存电路编程或擦除操作失效。
研究瞭閃存電路繫統中高壓電路的總劑量輻射效應(TID)。通過對內部高壓電荷泵電路和高壓負載電路的TID輻射效應測試研究,錶明輻照後高壓通路相關的存儲陣列及高壓晶體管漏電將造成電荷泵電路的負載電流過載失效,最終導緻閃存電路編程或抆除操作失效。

TheTIDradiationdegradationofhigh-voltagecircuitsintheflashmemorycircuitsystem is studied.We evaluates the effect of TID radiation to the internal high -voltage charge pumpings and their periphery circuits.The results show that the functional failures of charge pumping circuits are induced by the increasing leakage of memory array and high-voltage transistors after radiation,and leads to operation failure from the programming.
