Identify the programming mode of memory cells during reading of the memory cells

A computing device, comprising:

• a memory device having a controller and a plurality of memory cells;
• and
• at least one processor coupled to the memory device and configured to transmit, to the memory device, a command configured to instruct the memory device to store a data item into a predetermined number of first memory cells among the plurality of memory cells;
• the controller of the memory device is configured to program threshold voltages of the predetermined number of first memory cells to represent the data item and the first mode.

A memory device, comprising:

• a plurality of memory cells;
• a plurality of voltage drivers connected to memory cells;
• and
• a controller coupled to the voltage drivers configured to:
• read first memory cells among the plurality of memory cells,
• increase voltages driven by the voltage drivers across the first memory cells;
• and
• determine a programming mode of the first memory cells.
