Abstract
Memory blocks in an integrated circuit (IC) chip can be repaired by employing automated test equipment external to the IC chip to aid in burning fuses on the IC chip by encoding the fuses with binary-encoded numbers. Each binary-encoded number represents a bit position of each '1' bit of a repair control word corresponding to a defective memory location. During a repair sequence preceding operation of the IC chip, the binary-encoded numbers are read out of the fuses and used to form a serial stream of repair chain information.
