С уменьшением размеров транзисторов возникают условия, когда удар одной частицы затрагивает сразу несколько транзисторов в составе ячейки памяти. Вследствие этого при моделировании недостаточно учитывать один транзистор, в который непосредственно попадает частица. В работе рассмотрена полноразмерная 3D-модель двух n-канальных транзисторов, являющихся частью 6T-ячейки памяти, в которую ударяет заряженная частица. Предложен способ моделирования удара частицы, который позволяет ...
