SEMICONDUCTOR DEVICE AND METHOD OF OPERATING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 17895303 titled 'SEMICONDUCTOR DEVICE AND METHOD OF OPERATING THE SAME
Simplified Explanation
The patent application describes a semiconductor device that includes a one-time programmable (OTP) memory device, a key register, and key protection control logic. The OTP memory device stores a secret value, a key protection bit, and an end of life bit. The key register loads and stores the secret value, while the key protection control logic controls the loading of the secret value based on the key protection bit and the end of life bit. This enhances the security of the secret value and optimizes its utilization.
- The semiconductor device includes a one-time programmable (OTP) memory device.
- The OTP memory device stores a secret value, a key protection bit, and an end of life bit.
- A key register is present to load and store the secret value from the OTP memory device.
- Key protection control logic is used to control the loading of the secret value based on the key protection bit and the end of life bit.
- The key protection bit and the end of life bit enhance the security of the secret value and optimize its utilization.
Potential Applications
- Secure storage and protection of sensitive information.
- Authentication and encryption systems.
- Secure key management in various industries, such as finance, healthcare, and telecommunications.
Problems Solved
- Enhances the security of secret values stored in a semiconductor device.
- Provides control over the loading of secret values based on key protection and end of life indicators.
- Optimizes the utilization of secret values by allowing for protection and potential discarding of the semiconductor device.
Benefits
- Improved security for sensitive information.
- Efficient utilization of secret values.
- Flexibility in managing the lifecycle of the semiconductor device.
Original Abstract Submitted
A semiconductor device includes a one-time programmable (OTP) memory device, a key register and a key protection control logic. The OTP memory device stores a secret value, a key protection bit indicating whether to protect the secret value, and an end of life bit indicating whether to discard the semiconductor device. The key register loads the secret value from the OTP memory device and stores the secret value. The key protection control logic controls loading of the secret value from the OTP memory device to the key register based on the key protection bit and the end of life bit. Security of the secret value is enhanced and utilization of the secret value is optimized using the key protection bit and the end of life bit.
