    摘要: A flash memory device includes multiple memory blocks, a decoder configured to select at least one of the memory blocks in response to block select signals, a controller configured to generate the block select signals in response to a block address and to generate a flag signal when the block address corresponds to a bad block, and an output buffer configured to output fixed data in response to the flag signal indicating that the block address corresponds to the bad block. When the block address corresponds to a bad block, the controller generates the block select signals to cause the decoder to interrupt selection of a memory block corresponding to the block address.

    摘要: A non-volatile memory device according to embodiments of the invention includes a page buffer acting as a sense amplifier during a read operation and as a write driver during a program operation. The page buffer has two sense and latch blocks, which exclusively carry out the same function. While one of the sense and latch blocks carries out a read operation, the other sense and latch block outputs previously sensed data to the exterior. Further, while one of the sense and latch blocks carries out a program operation, the other sense and latch block loads data to be programmed. Due to the page buffer, an operation speed of the non-volatile memory device can be enhanced.
