20150074474 | SYSTEM AND METHOD FOR ON-THE-FLY INCREMENTAL MEMORY REPAIR - A device for repairing a memory device may include spare memory blocks that may replace corresponding memory blocks that include at least one non-operational memory cell. One or more registers may be coupled in a chain to store memory repair information. A memory repair module may identify, upon a power-up test of the memory device, non-operational memory cells, which are incremental to previously identified defective memory cells in previous power-up tests, and may provide corresponding memory repair information of the identified non-operational memory cells. A logic circuit may block access to one or more registers and may facilitate storing, in one or more unblocked registers, the corresponding memory repair information of the identified one or more non-operational memory cells. The memory repair module may swap a memory block including the identified non-operational memory cells with a spare memory block based on content of the one or more unblocked registers. | 03-12-2015 |
