Abstract
A method of cleaning-up a solid state memory disk is described. Clean-up begins with the selection of a focus block for clean-up. Next, on a sector-by-sector basis, memory is allocated within a destination block to store valid sectors of user data. User data is then copied into the destination block on a sector-by-sector basis. Afterward, the focus block is erased, converting dirty sectors into free memory without loss of valid sectors of data.
