Abstract
A memory system reads data from non-volatile memory cells using a set of read compare voltages to determine which data state the memory cells are in, where each data state is associated with predetermined data values. The read compare voltages are determined dynamically based on a difference between memory cell current at time of programming and memory cell current at time of reading.
