摘要： A device includes an anti-fuse (122) including a first electrode that can be selectively coupled to a first voltage reference (121) and a second electrode that can be selectively coupled to a second voltage reference (123). The device further includes a shunt transistor (124) including a first current electrode coupled to the first electrode of the anti-fuse (122), a second current electrode coupled to the second electrode of the anti-fuse (122), and a control electrode. The device additionally includes control logic (126) configured to disable the shunt transistor in response to a first program operation intended for the anti-fuse. The control logic (126) also is configured to enable the shunt transistor in response to a second program operation not intended for the anti-fuse.
