发明名称 Operating method of memory having redundancy circuitry
摘要 In a method of operating a memory circuit, which includes a plurality of memory arrays each coupled with a corresponding input/output (IO) interface and a redundancy memory page a failing address of a failing bit cell is determined. The failing address is located in a memory page of one of the memory arrays. The method further includes repairing the failing bit cell by replacing the memory page with the redundancy memory page.

主权项 1. A method of operating a memory circuit, the memory circuit comprising: a plurality of memory arrays each coupled with a corresponding input/output (IO) interface;at least one information row, anda redundancy memory page; the method comprising: determining a failing address of a failing bit cell, wherein the failing address is located in a memory page of one of the memory arrays;registering bits of the failing address in the at least one information row, wherein the at least one information row includes a plurality of word lines; andrepairing the failing bit cell by replacing the memory page with the redundancy memory page.
