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:
a data storage device configured to communicate with a host via multiple communication speeds, the data storage device including: a first controller configured to access data at a first memory, the first controller and the first memory distinct from the host; a second controller configured to access data at a second memory, the second controller and the second memory distinct from the host; and a third controller configured to:
receive a signal from the host;implement a first data communication protocol to communicate with the first controller when a first data communication speed associated with the signal is detected; andimplement a second data communication protocol to communicate with the second controller when a second data communication speed associated with the signal is detected, the first data communication speed being different than the second data communication speed.
