Abstract
In a data storage device with a multi-level-cell memory, bits of data are stored in different levels of each of the memory cells. In some situations, a quantized version of the stored data (e.g., the most-significant bits) may be requested. Responding to such a request can involve reading all levels of the memory cells to retrieve a full version of the data and then selectively providing only the quantized version. To improve performance, the data is stored in the memory in an interleaved manner in which the quantized version of the data is stored in the same level(s) instead of being spread across all levels of the memory cells. That way, when the quantized version of the data is later requested, only the relevant level(s) are sensed, thereby avoiding the time and resources needed to read memory level(s) that do not store the quantized data.
