    摘要: A multi-level solid state non-volatile memory array has memory cells that store data using a first number of digital levels. A controller of the memory array encodes a series of data bits to generate a series of encoded data bits, and converts the series of encoded data bits into a series of data symbols. The controller sends, to the memory array, a stored series of data symbols based on the series of data symbols for storage in a memory cell of the multi-level solid state non-volatile memory array. The controller generates an output signal based on data associated with the stored series of data symbols. The output signal is characterized by a second number of digital levels greater than the first number of digital levels. The controller outputs a series of output data symbols based on the output signal.
