Memory device with a row repair mechanism and methods for operating the same

Last updated:

Abstract:

Methods, apparatuses and systems related to managing access to a memory device are described. A memory device includes a plurality of banks that each include (1) a plurality of memory cells and (2) a plurality of redundant cells configured to replace one or more target memory cells in the plurality of memory cells. A set of shared fuses and latches may be used to store a row address for each repair that may be implemented in one of the plurality of banks. A shared match circuit coupled to the set of shared latches and the plurality of memory banks may be configured to at least partially implement a row repair for the row address for a bank associated with a commanded operation.
