摘要：
In a non-volatile memory array where the memory cells in a sector are programmed together and a plurality of sectors form a segment which are erased together, through the use of a free list linking entries in a register with each entry in a register corresponding to a free segment, a free list table is created which readily simplifies searches for segments that are available for erasure. In addition, through the creation of a segment number table and a count index, determination of particular valid sectors in particular segments can be readily identified.
