    Abstract: A redundancy circuit for a multiport memory device with first and second memories includes a fuse programming circuit, shared between the first and second memories, for programming a first redundant address. A first address compare circuit compares a received address for the first memory with the first redundant address. The first address compare circuit generates a redundant address selection signal when the received address is the same as the first redundant address. A second address compare circuit compares a second received address for the second memory with the first redundant address. The second address compare circuit generates a redundant address selection signal when the received address is the same as the first redundant address.
