Method and Structure for Implementing a Reprogrammable ROM |
摘要 |
A method and structure for implementing a reprogrammable read only memory (ROM), and a design structure on which the subject circuit resides are provided. A pair of fuse elements having different lengths are selectively arranged to define an initial bit state. A group of a plurality of the pairs of fuse elements defines a predetermined data pattern of ones and zeros, providing initial states stored in the reprogrammable ROM. The reprogrammable ROM is reprogrammed when needed by selectively blowing a selected fuse or selected fuses to change the data pattern stored in the ROM.
