Abstract

A data storage apparatus includes storage, and a controller including an internal voltage trimming circuit and controlling the storage in response to a request from a host. The trimming circuit may include an integral circuit sampling a difference between a test voltage output by a device under test and a reference voltage, generating an integral signal by integrating a sampled signal, and including an offset cancellation unit cancelling an offset from the sampled signal, a comparison circuit generating a comparison signal by comparing the integral signal with the reference voltage, a code generation circuit receiving an initial trimming code and generating preliminary trimming codes by increasing or decreasing the initial trimming code in response to the comparison signal, and a code average signal generation circuit generating the final trimming code by averaging the preliminary trimming codes for a given time and provide the final trimming code to the storage.
