Abstract:
A memory device having memory cells operates in a normal mode, a first self refresh mode, and a second self refresh mode. The first self refresh mode provides a self refresh operation for retaining data stored in the memory cells without an external command. The time required to return to the normal mode from the first self refresh mode is shorter than a reference time. The second self refresh mode also provides the self refresh operation, but a time required to return to the normal mode from the second self refresh mode is longer than the reference time. The normal mode provides a higher operating voltage to the memory cells than does the second self refresh mode.

Claim (Index 11):
A method of operating a memory device that includes a plurality of memory cells and operates in one of a normal mode, a first self refresh mode and a second self refresh mode, the first self refresh mode executing a self refresh operation for retaining data stored in the plurality of memory cells without an external command, a time required to return to the normal mode from the first self refresh mode is shorter than a reference time, the second self refresh mode executing the self refresh operation, and a time required to return to the normal mode from the second self refresh mode is longer than the reference time, the method comprising:\n in the normal mode, generating a first operating voltage having a first variable level and providing the first operating voltage to the plurality of memory cells, the first variable level being changed according to an operating temperature of the memory device; in response to the memory device entering the first self refresh mode, changing a level of the first operating voltage to a first fixed level and providing the first operating voltage to the plurality of memory cells, the first fixed level being maintained regardless of the operating temperature of the memory device; and in response to the memory device entering the second self refresh mode, changing the level of the first operating voltage to a second fixed level and providing the first operating voltage to the plurality of memory cells, the second fixed level being lower than the first variable level and the first fixed level and being maintained regardless of the operating temperature of the memory device.
