It has been argued that oxide breakdown (BD) may limit CMOS scaling [1], but its impact on circuit functionality is not clear. Oxide reliability models assume that a single BD on a chip will cause circuit failure, but even hard breakdown (HBD) does not cause complete failure of some circuits [2]. The circuit chosen for this investigation includes an SRAM cell, the bit select and the sense amplifier circuit (Fig. 1.a).
