Abstract
A storage controller includes a first on-die termination (ODT) circuit, a second ODT circuit and an ODT control circuit. The first ODT circuit provides a first termination resistance with a strobe signal line transferring a data strobe signal. The second ODT circuit provides a second termination resistance with at least one data line transferring data. The ODT control circuit individually controls activation and deactivation of the first ODT circuit and the second ODT circuit.
Claims17
A storage controller comprising:
- a first on-die termination (ODT) circuit that is configured to provide a first termination resistance with a strobe signal line that is configured to transfer a data strobe signal;
- a second ODT circuit that is configured to provide a second termination resistance with at least one data line that transfers data;
- and
- an ODT control circuit that is configured to individually control activation and deactivation of the first ODT circuit and the second ODT circuit,
- wherein the ODT control circuit activates the first ODT circuit and deactivates the second ODT circuit during a reception operation in which the storage controller receives the data from a nonvolatile memory device.

A solid state disk (SSD) comprising:
- a plurality of nonvolatile memory devices that store data;
- and
- a storage controller that is configured to control the plurality of nonvolatile memory devices,
- wherein the storage controller comprises:
- a first on-die termination (ODT) circuit that is configured to provide a first termination resistance with a strobe signal line that is configured to transfer a data strobe signal;
- a second ODT circuit that is configured to provide a second termination resistance with at least one data line that transfers the data;
- and
- an ODT control circuit that is configured to individually control activation and deactivation of the first ODT circuit and the second ODT circuit,
- wherein the ODT control circuit activates the first ODT circuit and deactivates the second ODT circuit during a reception operation in which the storage controller receives the data from the plurality of nonvolatile memory devices.

A device comprising:
- a storage controller that is configured to control a plurality of nonvolatile memory devices that are configured to store data,
- the storage controller comprising:
- a first on-die termination (ODT) circuit that is configured to provide a first termination resistance with a strobe signal line;
- a second ODT circuit that is configured to provide a second termination resistance with at least one data line that transfers the data, wherein the first termination resistance is different than the second termination resistance during a reception operation in which the storage controller receives the data from the plurality of nonvolatile memory devices;
- and
- an ODT control circuit that is configured to control activation and deactivation of the first ODT circuit and the second ODT circuit independently,
- wherein the storage controller comprises:
- a first receiver that includes the first ODT circuit and that receives the data strobe signal from a first channel;
- and
- a second receiver that includes the second ODT circuit and that receives the data from a second channel.
