Memory repair systems and methods for a memory having redundant memory
Abstract:
Memories, memory repair logic, and methods for repairing a memory having redundant memory are disclosed. One such memory includes programmable elements associated with respective redundant memory configured to have memory addresses mapped thereto, the programmable elements configured to be programmed with at least portions of the memory addresses. Such a memory further includes repair logic coupled to the programmable elements and configured to identify programmable elements available for programming to map memory addresses to respective redundant memory. One method for remapping a memory address of a memory to redundant memory includes receiving at least a portion of a memory address to be remapped to redundant memory, determining whether a programmable element associated with the redundant memory is available for programming, and when a programmable element is available, programming the programmable element such that the memory address will be mapped to the associated redundant memory.
