US 10,832,768 B2 · Data storage based on data polarity

Abstract

Methods, systems, and devices for storing and reading data at a memory device are described. A memory device may utilize one or more storage states to store data within a data word. The memory device may exhibit higher data leakage or more power consumption when storing or reading a first storage state compared to storing or reading one or more other storage states. In some cases, the memory device may generate a second data word corresponding to a first data word by modifying each symbol type of the first data word to generate a different symbol type for the second data word. A memory device may reduce the occurrence of a storage state associated with large data leakage, or high-power consumption, or both. Further, the memory device may generate and store an indicator indicating the transformation of a corresponding data word.

Dependent claims

A method, comprising:

receiving, from a host device, a first data word to be stored in a memory device;
determining, by the memory device, that the first data word satisfies a first storage state criterion of the memory device, the first storage state criterion indicating a first characteristic of one or more memory cells of the memory device;
generating a second data word that satisfies a second storage state criterion by applying a transformation to the first data word based at least in part on determining that the first data word satisfies the first storage state criterion, the second storage state criterion indicating a second characteristic of the one or more memory cells of the memory device;
and
storing the second data word in the memory device.
