Abstract
An E.sup.2 PROM redundant memory element is provided whereby faulty or improperly coded ROM or E.sup.2 PROM elements may be replaced by the user in-package. An address programming element including an E.sup.2 PROM floating gate device having a programmed mode, an unprogrammed mode, and an inhibit mode, may be programmed and erased in-package. Addresses received by the redundant memory element in addition to other inputs determine the mode of the floating gate device.
