SEMICONDUCTOR MEMORY DEVICE AND METHOD FOR CONTROLLING THE SAME |
摘要 |
A semiconductor memory device capable of reducing the size of a NAND flash memory device includes a latch unit configured to store a bad block address, a comparator configured to compare the bad block address with an access address so as to output a bad-block detection signal, and a bad block controller configured to sequentially output a plurality of bad block pulses corresponding to the bad-block detection signal during a predetermined period in response to a plurality of bad-block flag signals that are sequentially activated.
