FLASH MEMORY DEVICE REMAPPING BAD BLOCKS AND BAD BOLCK REMAPPING METHOD THEREOF

摘要

A flash memory device for remapping bad blocks and a bad block remapping method thereof are provided to reduce a chip area and to enhance utility of memory blocks by composing identically row decoder circuits of the memory blocks. A flash memory device for remapping bad blocks includes an address storage block(130) and an encoder. The address storage block detects whether a block address(BLK_Add) provided from the outside is identical with a pre-stored block address or not. The address storage block generates a repair signal(/REDn) according to the detected result. The encoder converts the repair signal to a block selection signal for selecting a normal memory block.
