IN-PACKAGE E2PROM REDUNDANCY

摘要

An E2PROM redundant memory element (10) whereby faulty or improperly coded ROM or E2PROM elements may be replaced by the user in-package. An address programing element (12) including an E2PROM floating gate device (20) 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.
