Abstract
A storage module and method for managing logical-to-physical address mapping are disclosed. In one embodiment, a storage module is provided comprising a memory having a plurality of wordlines and a controller. The controller is configured to use a logical-to-physical address map to convert a logical address to a physical address of a wordline. A plurality of logical addresses in the map point to a single wordline, and the single wordline contains both data associated with the plurality of logical addresses and information about where to find each of the plurality of logical addresses in the single wordline . Storing the information about where to find each of the plurality of logical addresses in the wordline itself avoids the delay and complexity of using a larger logical-to-physical address map or multiple maps.
