Patent number: 12009026Abstract: Systems and methods for precision writing of weight values to a memory capable of storing multiple levels in each cell are disclosed. Embodiments include logic to compare an electrical parameter read from a memory cell with a base reference and an interval reference, and stop writing once the electrical parameter is between the base reference and the base plus the interval reference. The interval may be determined using a greater number of levels than the number of stored levels, to prevent possible overlap of read values of the electrical parameter due to memory device variations.Type: GrantFiled: December 10, 2020Date of Patent: June 11, 2024Assignee: Intel CorporationInventors: Clifford Ong, Yu-Lin Chao, Dmitri E.

Publication number: 20230209799Abstract: Integrated circuit (IC) static random-access memory (SRAM) comprising pass-gate transistors and pull-down transistors having different threshold voltages (Vt). A pass-gate transistor with a higher Vt than the pull-down transistor, may reduce read instability of a bit-cell, and/or reduce overhead associated with read assist circuitry coupled to the bit-cell. In some examples, a different amount of a dipole dopant source material is deposited as part of the gate insulator for the pull-down transistor than for the pass-gate transistor, reducing the Vt of the pull-down transistor accordingly. In some examples, an N-dipole dopant source material is removed from the pass-gate transistor prior to a drive/activation anneal is performed. After drive/activation, the N-dipole dopant source material may be removed from the pull-down transistor and a same gate metal deposited over both the pass-gate and pull-down transistors.Type: ApplicationFiled: December 23, 2021Publication date: June 29, 2023Applicant: Intel CorporationInventors: Clifford Ong, Dan Lavric, Leonard Guler, YenTing Chiu, Smita Shridharan, Zheng Guo, Eric A.

Publication number: 20220253285Abstract: An analog multiplication circuit includes switched capacitors to multiply digital operands in an analog representation and output a digital result with an analog-to-digital convertor. The capacitors are arranged with a capacitance according to the respective value of the digital bit inputs. To perform the multiplication, the capacitors are selectively charged according to the first operand of the multiplication. The capacitors are then connected to a common interconnect for charge sharing across the capacitors, averaging the charge according to the charge determined by the first operand. The capacitor are then maintained or discharged according to a second operand, such that the remaining charge represents a number of “copies” of the averaged charge. The capacitors are then averaged and output for conversion by an analog-to-digital convertor. This circuit may be repeated to construct a multiply-and-accumulate circuit by combining charges from several such multiplication circuits.Type: ApplicationFiled: April 26, 2022Publication date: August 11, 2022Applicant: Intel CorporationInventors: Yu-Lin Chao, Clifford Lu Ong, Dmitri E.
