ABSTRACT:
A data memory has at least one memory location field with memory locations and a redundancy circuit that has at least one redundancy memory location is further provided. A redundancy selection line selector module that has at least one assignment memory in which an item of assignment information can be stored is also provided to the data memory. It being possible for at least one redundancy memory location to be assigned to at least one memory location on the basis of the assignment information. The assignment memory has an assignment memory location with a buffer for the purpose of holding the assignment information. In the known data memories, relatively long programming times are required when assigning redundancy memory locations to memory locations, depending on the programming method used. In the data memories according to the invention, the assignment information can be transferred from the buffer into the assignment memory location. As a result, redundancy memory locations can be assigned to defective memory locations quickly and with a low expenditure of energy.
