Abstract
A universal fuse latch device includes a latch circuit receiving an electrical signal for initializing the latch circuit to a first state; one or more legs connected at the latch node, with a first leg implementing a fuse type element capable of transitioning the latch from the first state to a second state; and a second leg including an anti-fuse type element, wherein the fuse latch is provided with a fuse resistance trip point to ensure adequate reading of one of the fuse and anti-fuse type elements. The universal fuse latch device may be part of a programmable fuse bank including a plurality of information fuse latches for storing redundancy information in a memory system and capable of being simultaneously interrogated. A master fuse control device comprising the universal fuse latch circuit is programmed in accordance with a priority of legs to be interrogated in the information fuse latches.
