Application: Semiconductor device, electronic device, and method of setting characteristics of electronic device (Patent ID: US20240106327A1)
The semiconductor device described in the patent includes a storage circuit connected to a regulator circuit and an electronic fuse controller. The electronic fuse controller reads values from electronic fuses to generate identification data identifying the characteristics of the regulator circuit. This identification data is then supplied to the storage circuit in a different period from the reading period. The device operates by receiving a clock signal from a clock generating circuit powered by the regulator output, and the storage circuit includes a volatile holding circuit to store the characteristics' values.
Additionally, the semiconductor device can switch between a setting mode and a normal operation mode, with the characteristics identified and stored in the setting mode and represented by the regulator circuit in the normal operation mode. The reading control circuit includes a majority circuit to generate a majority value from read values, and the clock generating circuit can stop and restart the clock signal based on requests from the reading control circuit and characteristic control circuit. Overall, the device allows for efficient identification and storage of regulator circuit characteristics using electronic fuses.
