Abstract:
A semiconductor memory device for suppressing a decrease of durability caused by erasure of a block unit or programming of a word unit is provided. A resistance change memory  100  includes a memory array  110  and a controller  120 . The memory array  110  stores data by a reversible and nonvolatile variable resistance element. When erasing a selected block of the memory array  110  in response to an external erasure command, the controller  120  sets an EF flag indicating the selected block is in an erasure state without changing block data. The controller  120  further includes a reading unit. The reading unit outputs data of a selected word or data indicating the erasure based on the EF flag when reading the selected word of the memory array  110  in response to an external reading command.

Claim (Index 4):
The semiconductor memory device according to  claim 1 , further comprising a programming unit, the programming unit responding to an external programming command and programming input data to the selected word of the memory array, the programming unit setting the first flag data to be in a non-erasure state.
