Patent number: 10580484Abstract: There is provided a semiconductor integrated circuit device that can generate a unique ID with the suppression of overhead. When a unique ID is generated, the potential of a word line of a memory cell in an SRAM is raised above the power supply voltage of the SRAM, and then lowered below the power supply voltage of the SRAM. When the potential of the word line is above the power supply voltage of the SRAM, the same data is supplied to both the bit lines of the memory cell. Thereby, the memory cell in the SRAM is put into an undefined state and then changed so as to hold data according to characteristics of elements or the like configuring the memory cell. In the manufacture of the SRAM, there occur variations in characteristics of elements or the like configuring the memory cell. Accordingly, the memory cell in the SRAM holds data according to variations occurring in the manufacture.Type: GrantFiled: January 28, 2019Date of Patent: March 3, 2020Assignee: RENESAS ELECTRONICS CORPORATIONInventors: Makoto Yabuuchi, Hidehiro Fujiwara

Patent number: 10581364Abstract: An output control unit controls a drive terminal for a BEMF detection object phase to a high-impedance state in a mask term. A BEMF detection unit detects a voltage of the drive terminal for the detection object phase when a center tap voltage is set as a reference as BEMF in a PWM on-term for remaining two phases per PWM period in the mask term and asserts a zero-crossing signal when the voltage is reduced to zero. A PWM fixing unit fixes the remaining two phases to the PWM on-terms in a first term from a predetermined timing after an amplitude level of BEMF becomes smaller than a BEMF threshold amplitude to assertion of the zero-crossing signal. The BEMF detection unit continuously detects BEMF in the first term.Type: GrantFiled: November 13, 2018Date of Patent: March 3, 2020Assignee: RENESAS ELECTRONICS CORPORATIONInventors: Minoru Kurosawa, Kichiya Itagaki
