Abstract
A program method for an e-fuse array circuit includes receiving an address and a multi-bit program data, programming the multi-bit program data in e-fuses designated by the address, reading a multi-bit read data from the e-fuses, and comparing bits of the multi-bit program data with bits of the multi-bit read data, wherein if the bits of the multi-bit program data are identical to the bits of the multi-bit read data, a program operation is terminated; and if the bits of the multi-bit read data are not identical to the bits of the multi-bit program data, then the programming of the multi-bit program data, the reading of the multi-bit read data, and the comparing of the bits are performed again.
