Data Coding Device for Memory Controller Performance and Size

The patent merges the memory controller functionality directly into the nonvolatile memory device, creating an integrated solution. The memory controller includes components such as a host interface, memory interface, and data coding device, all integrated within the memory device itself. This integration eliminates the need for a separate memory controller chip, thereby improving performance and power efficiency while avoiding additional device size increase in portable applications.

The memory device is designed to perform multiple functions: it acts as both the nonvolatile memory storage and the memory controller. The device can manage data encoding, error correction, and communication with host devices, making it a universal component that replaces multiple separate components. This multi-functionality approach improves overall system performance while reducing the total device footprint.

The data coding device is integrated within the memory controller structure, combining encoding functionality with the memory management components. This integration allows shared use of circuitry and resources, improving processing capability while minimizing the additional area required for coding operations.

The patent employs adjustable coding parameters and configurable data processing modes that can be optimized for different performance requirements. By changing operational parameters rather than adding fixed hardware for all possible coding scenarios, the device achieves high processing capability with reduced area overhead.
