Memory cell read threshold voltage optimization

A system for determining an optimal read voltage for reading a set of memory cells of a memory device, comprising:

• the memory device;
• and
• a processing device coupled to the memory device, the processing device to perform operations comprising:
• providing a plurality of read voltages having different amplitudes to each of the memory cells;
• reading an output of each of the memory cells in response to each of the read voltages of the plurality of voltages;
• determining an approximate amplitude of a threshold voltage of each of the memory cells based on the output of each of the respective memory cells in response to each of the read voltages to generate a plurality of codewords, each of the codewords being associated with a respective one of the read voltages;
• implementing a decoding process on each of the codewords to determine a syndrome weight of each of the codewords;
• and
• determining the optimal read voltage based on one of the codewords associated with a respective one or more of the read voltages having a lowest value of the syndrome weight.
