Abstract
Techniques for producing and utilizing temperature compensated voltages to accurately read signals (e.g., voltages) representing data stored in memory cells of a memory system are disclosed. The memory system is, for example, a memory card. The magnitude of the temperature compensation can be varied or controlled in accordance with a temperature coefficient. These techniques are particularly well suited for used with memory cells that provide multiple levels of storage.
