CONTROLLER, DATA STORAGE DEVICE, AND DATA COMMUNICATION SYSTEM HAVING VARIABLE COMMUNICATION SPEED

摘要

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.

1. An apparatus comprising:
an interface to receive commands and data from a host; a system bus configured to communicate with a first memory, the first memory distinct from the host; a data storage area configured to store settings corresponding to a plurality of communication protocols; a processor configured to:
determine a data communication speed between the interface and the host;selectively implement a first data communication protocol from the plurality of communication protocols to communicate with the first memory or a second data communication protocol from the plurality of communication protocols to communicate with the first memory based on the determined data communication speed;store data in the first memory via the system bus using the first data communication protocol when the determined data communication speed is a first speed; andstore data in the first memory via the system bus using the second data communication protocol when the determined data communication speed is a second speed different than the first speed.
