Die-based rank management

This document describes apparatuses and techniques for die-based rank management for a memory system. In various aspects, a die-based rank controller (controller) can determine which memory dies of a memory device are not functional to store data and correlate rank selections of a memory system to ranks of other memory dies (e.g., functional memory dies). The controller may store information that indicates the correlation or mapping of the rank selections to the ranks of the other memory dies to enable access to those ranks of the memory system. In some aspects, the controller receives a command to access the memory device with a rank selection, and the controller enables access to a corresponding rank based on the information. By so doing, aspects of die-based rank management enable memory packages with non-functional memory dies to be used instead of discarded, which can increase production utilization or lower manufacturing costs.
