Weight verification circuit for neural memory cells
A recently granted patent (Publication Number: US11972795B2) discloses a circuit and method for verifying non-volatile memory cells. The circuit includes a digital-to-analog converter to convert a target weight represented by digital bits into a target voltage, a current-to-voltage converter to convert the output current from a selected non-volatile memory cell during a verify operation into an output voltage, and a comparator to compare the output voltage to the target voltage during the verification process.
The method outlined in the patent involves converting the digital bits representing the target weight into a target voltage, converting the output current from the selected non-volatile memory cell into an output voltage during verification, and comparing these voltages to ensure accuracy. The process utilizes a digital-to-analog converter for the conversion of the target weight and a current-to-voltage converter for the conversion of the output current from the memory cell. This innovative approach aims to enhance the efficiency and reliability of verifying non-volatile memory cells, potentially leading to advancements in memory technology.
