Zusammenfassung:Embodiments disclosed include redirecting data from a defective data entry in memory to a redundant data entry prior to data access. Related systems and methods are also disclosed. The memory is configured to receive a memory access request. The received memory access request comprises a data entry address. The memory uses the data entry address to access data stored in a data array in the memory in a first data access path. It is possible that the rows or columns in the memory may be defective as a result of a manufacturing process. In the event that a row or column at the data entry address in the data array is defective, a data entry redirection circuit redirects the memory access request to a redundant row or column in the data array prior to data access.
