Modifiable repair solutions for a memory array

Abstract:

Methods, systems, and devices for modifiable repair solutions for a memory array are described to support storing repair information for a memory array within the memory array itself. A memory device may include the memory array and an on-die microprocessor, where the microprocessor may retrieve the repair information from the memory array and write the repair information to repair circuitry used for identifying defective memory addresses. The microprocessor may support techniques for identifying additional defects and updating the repair information during operation of the memory array. For example, the microprocessor may identify additional defects based on errors associated with one or more memory cells of the memory array or based on testing performed on one or more memory cells of the memory array. In some cases, a host device may identify additional defects and may notify the microprocessor of the additional defects.
