PHASE-CHANGE RANDOM ACCESS MEMORY AND BOOT BLOCK SETTING METHOD THEREOF

摘要

A phase change memory device and a boot block setting method thereof are provided to set a boot block size of a word unit, thereby reducing waste of a memory space. A phase change memory device(400) comprises a memory cell array(420). The memory cell array comprises a plurality of memory blocks(BLK 11~BLK n2). The phase change memory device stores boot data required for booting a part or all of memory blocks. The memory blocks storing boot data of the phase change memory device includes at least one setting unit(R1~R7). The setting unit forms a part or all of the memory blocks. The memory blocks corresponding to the setting units are formed. A size of a boot data storage area corresponds to the number of the setting units of the memory block having the boot data storage area.
