Abstract
One or more mapping data structures are maintained containing mappings of logical flash memory addresses to physical flash memory addresses. Each mapping data structure has a predetermined capacity of mappings. A master data structure is also maintained containing a pointer to each of the one or more mapping data structures. Additional mapping data structures are allocated as needed to provide capacity for additional mappings. Each time a mapping data structure is allocated or de-allocated the pointers in the master data structure are changed accordingly.
