Summary:Disclosed herein is an architecture that pairs a controller with a NVM (non-volatile memory) storage system. The NVM storage system includes a bridge device that communicates with the controller. In one embodiment, the bridge device allows for certain data locations (blocks, pages or units at any other granularity) in the flash dies to be (1) placed into a reserved mode where data access is prevented (2) assigned into an SLC (Single-Level Cell) mode or an MLC (Multi-Level Cell) mode in response to controller command, (3) made available for data access after the assignment of mode. This flexibility enables the controller to increase SLC mode or MLC mode data locations based on run-time conditions. In one embodiment, the assignment of the reserved data locations is performed in a way to ensure that warranty conditions imposed by the memory vendors are observed.
