ABSTRACT
Although fail bit maps in burn-in memory testers are important for analyzing process problems,we need very large storage for storing them. This paper present a method for compressing fail bit maps and storing them catch rams. We classify fail patterns under six types. Catch ram stores the fail types and their locations. Since proposed method is simple, it can be easy implemented in hardware on every DUT(device under test) board. A prototype has been developed by using an FPGA and an SRAM.
