    摘要: A read only memory (ROM) with redundancy and methods of use are provided. The ROM with redundancy includes a programmable array coupled to a repair circuit having one or more redundant repairs. The one or more redundant repairs include a word address match logic block, a data I/O address, and a tri-state buffer. The word address match logic block is provided to the tri-state buffer as a control input and the data I/O address is provided to the tri-state buffer as an input. An output of the tri-state buffer of each redundant repair is provided as a first input to one or more logic devices. One or more data outputs of a ROM bit cell array is provided as a second input to a respective one of the one or more logic devices.

    摘要: A design structure for providing optimal fuse programming conditions by which an integrated circuit chip customer may program electronic fuses in the field, i.e., outside of the manufacturing test environment. An optimal fuse programming identifier, which is correlated to optimal fuse programming conditions, may be provided to the customer in readable fashion on the customer's IC chip. Accessing the optimal fuse programming identifier on the customer's IC chip, the customer may apply a fuse programming process in the field according to one or more correlated optimal fuse programming conditions.
