STORAGE DEVICES AND METHODS OF OPERATING STORAGE DEVICES - A simplified explanation of the abstract
This abstract first appeared for US patent application 17750581 titled 'STORAGE DEVICES AND METHODS OF OPERATING STORAGE DEVICES
Simplified Explanation
The patent application describes a storage device that includes a nonvolatile memory device and a storage controller. The memory device has a memory cell array divided into memory blocks, and the storage controller controls the memory device.
- The memory cell array is divided into memory blocks using word-line cut regions.
- The storage controller includes an error correction code (ECC) engine.
- The ECC encoder in the ECC engine performs ECC encoding on sub data units in user data to generate parity bits.
- The ECC encoder also generates multiple ECC sectors.
- The ECC encoder selects outer cell bits to be stored in outer cells and creates an outer ECC sector.
- The ECC encoder performs a second ECC encoding operation on the outer ECC sector to generate outer parity bits.
- The memory interface in the storage controller transmits a codeword set to the nonvolatile memory device.
- The codeword set includes the ECC sectors and the outer parity bits.
Potential applications of this technology:
- Data storage devices such as solid-state drives (SSDs) and flash memory devices.
- Cloud storage systems.
- Data centers and server farms.
Problems solved by this technology:
- Data corruption and loss during storage and transmission.
- Improving data reliability and integrity.
- Reducing the impact of errors on stored data.
Benefits of this technology:
- Enhanced error correction capabilities.
- Improved data integrity and reliability.
- Efficient use of storage space.
- Increased storage capacity.
- Faster data transmission and retrieval.
Original Abstract Submitted
A storage device includes a nonvolatile memory device including a memory cell array and a storage controller to control the nonvolatile memory device. The memory cell array includes word-lines, memory cells and word-line cut regions dividing the word-lines into memory blocks. The storage controller includes an error correction code (ECC) engine including an ECC encoder and a memory interface. The ECC encoder performs a first ECC encoding operation on each of sub data units in user data to generate parity bits and generate a plurality of ECC sectors, selects outer cell bits to be stored in outer cells to constitute an outer ECC sector including the outer cell bits and performs a second ECC encoding operation on the outer ECC sector to generate outer parity bits. The memory interface transmits, to the nonvolatile memory device, a codeword set including the ECC sectors and the outer parity bits.
