Abstract
A thermodynamic RAM technology stack, two or more memristors or pairs of memristors comprising AHaH (Anti-Hebbian and Hebbian) computing components, and one or more AHaH nodes composed of such memristor pairs that form at least a portion of the thermodynamic RAM technology stack. The levels of the thermodynamic-RAM technology stack include the memristor, a Knowm synapse, an AHaH node, a kT-RAM, kT-RAM instruction set, a sparse spike encoding, a kT-RAM emulator, and a SENSE Server.
Claims13
Thermodynamic RAM (Random Access Memory), comprising:
- an AHaH (Anti-Hebbian and Hebbian) circuit comprising synaptic inputs and at least one MSS (Metastable Switch) memristor, wherein said AHaH circuit is superimposed above at least one RAM core having bits, such that said synaptic inputs of said AHaH circuit are turned on in the same order in which said bits are set in said at least one RAM core;
- and
- a plurality of memristive synapses comprising said synaptic inputs, said plurality of memristive synapses configured from said at least one MSS memristor, wherein said thermodynamic RAM performs an analog sum of currents based on an instruction set and said plurality of memristive synapses adapt physically by weight adaptation according to AHaH plasticity, which eliminates a need to compute and write memory updates, and wherein forward and reverse instructions thereof are paired to prevent weight saturation.
