Abstract
Apparatuses having variable communication speeds are disclose. In one example, an apparatus may comprise a controller configured to: receive a signal from a host, the signal being compatible with a data communication protocol at a first data communication speed; selectively implement a first data communication protocol from a plurality of data communication protocols to communicate with a first memory or implement a second data communication protocol from the plurality of data communication protocols to communicate with a second memory based on the data communication speed; store data in the first memory via the first data communication protocol when the data communication speed is a first speed; and store data in the second memory via the second data communication protocol when the data communication speed is a second speed that is different than the first speed.
