Abstract
A data storage device includes a memory and a controller. Read voltages are updated based on adjusting a first read voltage without adjusting a second read voltage to generate multiple sets of read voltages, and the multiple sets of read voltages are used to generate multiple representations of data. A value of the first read voltages is selected based on error correction coding (ECC) related information related to the multiple representations of the data. In another embodiment, storage elements of the memory are sensed using a set of candidate read voltages to generate sensing data that is transferred to a memory accessible to the controller. The multiple representations of data may be generated based on the sensing data to emulate results of reading the storage elements using a different combination of candidate reading voltages.
