ABSTRACT:
A method for quickly identifying floating cells by a bit-line coupling pattern (BLCP), an electronic analysis method, identifies floating cells by inputting different background data and inducing net charges from adjacent bit-lines to the bit-lines corresponding to floating cells by coupling parasitic capacitors, wherein the floating results from open bit-line contacts and/or open DRAM cell contacts. Moreover, a method for identifying floating cells according to the invention has the advantages of high efficiency and low cost.
