SEMICONDUCTOR MEMORY DEVICE |
| 摘要 |
A semiconductor memory device includes a first pad which outputs data to the outside; an output driver coupled to the first pad; a calibration circuit which adjusts impedance of the output driver; and a controller. The controller controls a calibration operation by the calibration circuit, in response to a first command received from the outside, and performs a write operation on a mode resister, in response to a second command received from the outside, the second command being different from the first command. |
