Abstract:
Methods, systems, and devices for techniques for determining memory cell read offsets are described to support determining voltage offsets and corresponding read voltage levels for one or more memory cell levels using a relationship between read voltage levels and voltage offsets. A memory device may estimate first voltage offsets using a first procedure and may perform a read operation using the first voltage offsets. If a first voltage offset results in a read error for a corresponding memory cell level, the memory device may determine an updated voltage offset using the relationship. The relationship may predict a voltage offset for a given read voltage level, such that the memory device may use the relationship to predict an updated voltage offset for a memory cell level. The memory device may use the updated voltage offset(s) to perform a second read operation for the one or more memory cells.
