STORAGE DEVICE AND OPERATING METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 18139719 titled 'STORAGE DEVICE AND OPERATING METHOD THEREOF
Simplified Explanation
The abstract describes a storage device that includes a nonvolatile memory, a memory controller, and a physically unclonable function (PUF) circuit. The PUF circuit generates PUF data based on the output of a specific memory cell group, excluding outputs from certain exclusion areas with different threshold voltages.
- The storage device includes a nonvolatile memory divided into first and second memory cell groups.
- It also includes a memory controller and a physically unclonable function (PUF) circuit.
- The PUF circuit generates PUF data based on the output of the second memory cell group.
- The PUF data is generated by excluding outputs from three exclusion areas.
- The first exclusion area has a threshold voltage between a first and second read level.
- The second exclusion area has a threshold voltage lower than a third read level.
- The third exclusion area has a threshold voltage higher than a fourth read level.
Potential applications of this technology:
- Secure storage devices: The PUF circuit can be used to generate unique and unclonable identifiers for secure storage devices, enhancing their security.
- Authentication systems: The PUF data generated by the circuit can be used for authentication purposes, ensuring the integrity and authenticity of data or devices.
- Anti-counterfeiting measures: The PUF data can be utilized to create unique identifiers for products, making it difficult for counterfeiters to replicate them.
Problems solved by this technology:
- Cloning prevention: The PUF circuit generates unique data that cannot be easily replicated, providing a solution to prevent cloning or unauthorized copying of storage devices or other products.
- Secure authentication: The PUF data can be used for secure authentication, ensuring that only authorized users or devices can access certain data or systems.
Benefits of this technology:
- Enhanced security: The PUF circuit adds an additional layer of security by generating unique and unclonable data, making it difficult for attackers to compromise the system.
- Improved authentication: The PUF data can be used for robust and secure authentication, reducing the risk of unauthorized access or data breaches.
- Counterfeit prevention: By utilizing the PUF data for unique product identification, this technology helps in preventing counterfeiting and protecting brand reputation.
Original Abstract Submitted
A storage device is provided. The storage device includes: a nonvolatile memory including memory cells divided into first and second memory cell groups; a memory controller; and a physically unclonable function (PUF) circuit configured to generate PUF data, based on an output of the second memory cell group, by excluding, from the output of the second memory cell group, outputs of a first exclusion area, a second exclusion area, and a third exclusion area, The first exclusion area has a threshold voltage equal to or greater than a first read level and less than a second read level, the second exclusion area has a threshold voltage less than a third read level that is less than the first read level, and the third exclusion area has a threshold voltage equal to or greater than a fourth read level that is greater than the second read level.
