INTEGRATED CIRCUIT AND DATA INPUT METHOD |
摘要 |
An integrated circuit includes a data input such as a data pad for receiving an external data signal input and an on-die termination (ODT) information input for receiving ODT information from an external device. An ODT circuit selectively couples a termination resistor to the data pad based on the ODT information. An input buffer is coupled to the data pad for determining data that is input into the pad using a reference voltage. A reference voltage generator is coupled to the input buffer and generates the reference voltage on the basis of the ODT information. |

1. An integrated circuit comprising:
a pad configured to receive an external data signal input; an on-die termination (ODT) information input configured to receive ODT information from an external device; an ODT circuit configured to selectively couple a termination resistor to the pad based on the ODT information; an input buffer coupled to the pad and configured to determine a data value based on a reference voltage; and a reference voltage generator coupled to the input buffer and configured to generate the reference voltage based on the ODT information. |
