SWITCHABLE LANE DIRECTIONS BETWEEN A HOST SYSTEM AND A MEMORY SYSTEM

Methods, systems, and devices supporting switchable lane directions between a host system and a memory system are described. A host system may communicate with a memory system using a set of lanes, where each lane may send information (e.g., commands, operations, data) in a specific direction. In some cases, the host system and memory system may support one or more switchable lanes, where both systems include transmit and receive modules for the lane. According to a bandwidth condition associated with a specific direction satisfying a threshold for reconfiguring a lane, the host system and the memory system may switch a direction configured for a lane. Switching the lane direction may increase the supported bandwidth in a specific direction, for example, from the host system to the memory system (e.g., in a "write optimized" configuration) or from the memory system to the host system (e.g., in a "read optimized" configuration).
