Methods, systems, and devices for analog storing information are described herein. Such methods, systems and devices are suitable for synaptic weight storage in electronic neuro- biological mimicking architectures. A memory device may include a plurality of memory cells each respective memory cell in the plurality of memory cells with a respective programming sensitivity different from the respective programming sensitivity of other memory cells in the plurality. Memory cells may be provided on different decks of a multi-deck memory array. A storage element material of a respective memory cell may have a thickness and/or a composition different from another thickness or composition of a respective storage element material of another respective memory cell on a different deck in the multi-deck memory array. The memory device may further include reading circuitry configured to analogically read respective information programmed in the respective memory cells and to provide an output based on a combination of the respective information analogically read from the respective memory cells.
