Abstract
A method of controlling access to a flash memory device having multiple sectors divided into multiple blocks of memory, including accepting a virtual block address, calculating a set of possible sectors that can be used for storing data having the virtual block address based on a predefined function, reading meta-data of each sector from the set of possible sectors, wherein the meta-data of a sector includes information for each block in the sector indicating if the block is currently in use and the virtual block address of the data stored in the block, determining the physical block address of the virtual block address if the data is currently stored in a block in the possible sectors or if a block is currently allocated to store the data, wherein the set of possible sectors is distinct for each virtual block address.
