The invention relates to a zoom lens that can achieve higher performance easily. In one embodiment, a network is mapped, comprising: converting network line data into point data; associating the point data with cells of a grid overlaying the network; and analyzing the network by determining the relationship of the point data to the cells of the grid. The managing further includes initializing the slave middleware as slave middleware threads by the main middleware thread, such that each initialized slave middleware thread functions independently of the main middleware thread. With reduced fuse count, the yield of the memory chip’s die may also be improved because of less number of defective fuses or failed fuse blows.
