Fault repair controller for redundant memory integrated circuits |
摘要 |
A controller for repairing a redundant memory circuit includes a fault storage matrix for mapping a repair solution, a plurality of registers for storing row and column coordinates of the repair solution, and a repair solution calculator coupled to the plurality of registers and the fault storage matrix for receiving an x-coordinate and a y-coordinate of a defective memory cell in the redundant memory circuit and for determining whether a repair solution may be found from the fault storage matrix.
