PHYSICAL COORDINATE TRANSFORMATION SYSTEM OF PHYSICAL ADDRESS OF MEMORY CELL, COORDINATE TRANSFORMATION METHOD AND RECORDING MEDIUM STORING COORDINATE TRANSFORMATION PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a method for preparing a transformation table for transforming fail bit map data in the test process of a semiconductor memory into physical coordinates using design data. ;SOLUTION: The method for forming a conversion table comprises a step (S107) for defining an placement pattern of memory cells being repeated a plurality of times as a basic pattern, a step (S107) for associating the local physical address of the memory cell with physical coordinates, a step (S109) for grouping the memory cells based on a basic pattern, and a step (S111) for associating the physical address at the origin of a basic pattern referring to the origin of all memory cells with physical coordinates.;COPYRIGHT: (C)2001,JPO
