Zusammenfassung:	This application provides a memory, a chip, and a method for storing repair information of a memory. The memory includes: a repair circuit, configured to receive a first signal from a processor, and determine to be powered by a first power supply or a second power supply based on a status of the first signal, to store repair information, where the repair information is information of a failed bit cell in the memory, the first power supply is zero or in a high impedance state when a system is powered off, and the second power supply is not zero when the system is powered off; and a processing circuit, configured to perform communication between the memory and the processor based on the repair information. Therefore, the repair information of the memory can be continuously stored.
