Described embodiments provide a media controller that processes requests including a logical address and address range. A map of the media controller determines physical addresses of a media associated with the logical address and address range of the request. The map is a multi-level map having a plurality of leaf-level map pages that are stored in the media, with a subset of the leaf-level map pages stored in a map cache. Based on the logical address and address range, it is determined whether a corresponding leaf-level map page is stored in the map cache. If the leaf-level map page is stored in the map cache, a cache index and control indicators of the map cache entry are returned in order to enforce ordering rules that selectively enable access to a corresponding leaf-level map page based on the control indicators and a determined request type.
