Analog storage using memory device

Abstract

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.
