Abstract
A memory device which can perform various memory tests without increasing a size of the memory device. The memory device includes: a first pad for receiving external ROM data from a memory controller; a second pad for receiving an external clock signal corresponding to the external ROM data from the memory controller; and a control logic connected to the first pad and the second pad and configured to perform an operation corresponding to the external ROM data in response to the external clock signal in a test mode.
Claims19
A memory device comprising:
- a first pad configured to receive external ROM data from a memory controller, the external ROM data received from outside of the memory device;
- a second pad configured to receive an external clock signal corresponding to the external ROM data from the memory controller, the external clock signal received from outside of the memory device;
- and
- a control logic connected to the first pad and the second pad and configured to perform an operation corresponding to the external ROM data and in synchronization with the external clock signal in a test mode.
