DATA STORAGE DEVICES USING NON-VOLATILE MEMORY DEVICES AND OPERATING METHODS THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 18052344 titled 'DATA STORAGE DEVICES USING NON-VOLATILE MEMORY DEVICES AND OPERATING METHODS THEREOF
Simplified Explanation
The abstract describes an operating method for a data storage device that includes a buffer memory, a non-volatile memory, and a controller. The method involves receiving an encryption request from a host for data stored in the buffer memory and performing an encryption operation in response to the request. The encryption operation includes a program operation where a physical address of a buffer region in the non-volatile memory is received, encrypted data is generated using an encryption module in the controller, and the encrypted data is programmed into the buffer region based on the physical address.
- The method involves encrypting data stored in a buffer memory of a data storage device.
- The encryption operation includes a program operation where encrypted data is generated and programmed into a specific buffer region of a non-volatile memory.
- The encryption request is received from a host, indicating the need for data encryption.
- The encryption module in the controller is activated to perform the encryption operation.
- The physical address of the buffer region in the non-volatile memory is used to determine where the encrypted data should be stored.
Potential Applications
- Data security and protection in various storage devices, such as solid-state drives (SSDs) or USB drives.
- Secure data transfer and storage in cloud computing environments.
- Protection of sensitive information in embedded systems, such as IoT devices or industrial control systems.
Problems Solved
- Provides a method for encrypting data stored in a buffer memory, enhancing data security.
- Enables secure storage and transfer of sensitive information, protecting it from unauthorized access.
- Simplifies the encryption process by utilizing a controller and encryption module within the data storage device.
Benefits
- Enhanced data security and protection against unauthorized access.
- Efficient encryption process performed within the data storage device itself.
- Simplified implementation of data encryption in various storage devices.
- Enables secure storage and transfer of sensitive information in different applications.
Original Abstract Submitted
An operating method of a data storge device including a buffer memory, a non-volatile memory, and a controller, includes receiving, from a host, an encryption request for data stored in the buffer memory, and performing an encryption operation in response to the encryption request, wherein the performing of the encryption operation comprises performing a program operation, the performing of the program operation comprises receiving a physical address of a buffer region of the non-volatile memory, generating encrypted data by causing an encryption module included in the controller to be in an on state to encrypt the data stored in the buffer memory, and programming the encrypted data in the buffer region of the non-volatile memory based on the physical address.
