FLASH MEMORY DEVICE AND METHOD FOR CHANGING A BLOCK SIZE USING ADDRESS SHIFTING

摘要

A flash memory device for changing block size using address shifting is provided to change the block size internally, by merging blocks located in different planes and then separating the merged blocks, by shifting least significant bit of a block address to least significant bit of a page address or least significant bit of the page address to least significant bit of the block address. According to a method for changing block size in a flash memory device having a multi-plane structure, an external input address is decoded to a block address and a page address. Block size of the flash memory is changed from a first block size to a second block size, by shifting a bit of the block address to a bit of the page address, or a bit of the page address to a bit of the block address.
