FIXED WEIGHT CODEWORDS FOR TERNARY MEMORY CELLS

Methods, systems, and devices for fixed weight codewords for ternary memory cells are described. A memory device may generate a codeword from a set of data bits and invert a portion of the codeword so that the codeword is associated with a target distribution of programmable states.

Summary:Methods, systems, and devices for fixed weight codewords for ternary memory cells are described. A memory device may generate a codeword from a set of data bits and invert a portion of the codeword so that the codeword is associated with a target distribution of programmable states. After inverting the portion of the codeword, the memory device store the codeword in a set of ternary cells according to a coding scheme. The memory device may read the codeword from the set of ternary cells and select one or more reference voltages for the set of ternary cells based on the target distribution for the codeword and the states of the ternary cells.
