Abstract
A memory system is described which employs a plurality of 'mostly good' memory chips. A redundant memory chip is used to store data designated to the defective locations in the mostly good memories. In one embodiment a PROM is programmed to recognize the addresses of the defective elements and to cause the redundant memory to be selected. In another embodiment, a content-addressable memory is employed to provide a new address in response to the addresses of defective elements in the mostly good memories.
