Abstract
Technology is described herein that provides a partial reset of a non-volatile memory controller. In one aspect, a non-volatile memory controller persists memory addresses of I/O queues across a partial reset of the non-volatile memory controller. The non-volatile memory controller may also persist a mapping between each I/O submission queue and a corresponding I/O completion queue across the partial reset. Persisting the addresses of the I/O queues and/or mappings alleviates the need for a host system and non-volatile memory controller to perform a lengthy process of sharing the addresses of the I/O queues and/or mappings.
