Abstract
A memory device includes a cell area having N+1 unit cell blocks. Each cell block includes M word lines. The N unit cell blocks are each corresponded to a logical cell block address. The one additional unit cell block is added for accessing data with high speed. A tag block receives a row address, senses the logical cell block address in the row address and outputs a physical cell block address based on the logical cell block address and the candidate information. The tag block includes:N+1 unit tag tables corresponding to the N+l unit cell blocks. Each tag block has M number of registers. The M number of registers correspond to M number of word lines of the corresponding unit cell blocks. Each register stores one logical cell block address. The tag block also includes an initialization unit that initializes the N+1 unit tag tables.
