ABSTRACT:
A controller continuously or periodically interrogates the FAT table to determine which blocks are not storing data relative to any files stored in the memory at that time. If a block is located that is not allocated to a file, this block is erased and marked as being ready to receive data. In this way, a large file can be stored in the memory without having to wait for an erase operation to take place while the file is being written to the memory.
