A multi-bit memory device with a memory cell means for storing input information for an indefinite period of time. The multi-bit memory means stores information in up to Kn memory states (Kn>1). A memory cell programming means and comparator means is also included. The present multi-bit memory device also includes a voltage divider arrangement with pull-up devices in a memory array to provide stable and accurate reference voltages over process, temperature, and voltage variations.
