San Jose State University Research Foundation Assigned Patent

San Jose State University Research Foundation, San Jose, CA, has been assigned a patent (12334150) developed by Le; Binh Quang, San Jose, CA, for a “synaptic array for field-training-capable in-memory computing using non-volatile memory technologies.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “An apparatus and system are described to provide an in-memory computing non-volatile flash memory cell array used in a neural network. Each cell includes a Resistive RAM memory (RRAM) and a physical resistor formed from a high resistive material. The RRAM is programmed to either an on or off state in which the resistance is respectively significantly less or more than the resistor to permit the RRAM to act as a switch and allow for in-situ training. Multi-bit RRAM cells contain multiple RRAMs, each of which is connected to a resistor having a different resistance and read using the same input line. The resistors are formed from the same material as the resistor in the analog-to-digital converter used to read the array.”

The patent application was filed on 2023-03-23 (18/188978).
