SEMICONDUCTOR MEMORY DEVICE AND METHOD OF PROCESSING DATA FOR ERASE OPERATION OF SEMICONDUCTOR MEMORY DEVICE
摘要:
A semiconductor memory device comprises a plurality of memory blocks, and erase flag storage block storing erase flag information to indicate erase states of the plurality of memory blocks. The erase flag information can be used to monitor completion of erase operations of the memory blocks and to update erase count information of the memory blocks.
