    摘要: In one embodiment, a non-volatile memory device includes a plurality of protection bits denoting that an area of memory in the device must be protected from being erased or programmed. The memory device further includes a majority logic circuit for determining the logic state of the majority of the plurality of protection bits. Another embodiment includes a pattern generator for generating the logic levels to be stored in the plurality of protection bits.

    摘要: The fuse and latch circuit has a Floating gate Avalanche injection Metal Oxide Semiconductor (FAMOS) transistor (fuse) that is coupled to a read circuit. The read circuit includes circuitry that reduces the drive strength of the fuse. A transmission gate couples the read circuit to the latch circuit. The transmission gate isolates the fuse from the latch. When a reset condition occurs, the data that was in latch circuit remains after the reset condition is complete.

    摘要: Memory devices and methods of operating memory devices provide for using differing potentials during erase verify operations facilitate normal erase operations and subsequent erase check operations. Such apparatus and methods facilitate subsequent checks for data gain of erased memory cells using abbreviated procedures compared to normal erase operations.
