Abstract
A memory controller that performs address replacement using combinational logic. A dedicated buffer receives a target address corresponding to a memory operation instruction. Another dedicated buffer holds a problem address. Yet another dedicated buffer holds a repair address to be used to replace the problem address when memory operations instructions are targeted at that problem address. An address compare combinational circuit compares a received target address held by the dedicated target address buffer with a problem address held by the dedicated repair address buffer. If there is a match, the address compare combinational circuit generates a match notification signal. In response to a match notification signal, an address circuit, which may also be a combinational circuit, responds by causing the repair address within the dedicated repair address buffer to be targeted by the memory operation instruction instead of the problem address being targeted.
