Flash Memory Address Mapping for Variable Block Sizes

The patent implements dynamic block size determination by introducing a block size determining unit that selects appropriate block sizes based on the actual data access patterns and requirements of host systems. Instead of using a fixed block size for all operations, the system dynamically adjusts the block size to match the specific access scenario, thereby improving data processing performance while maintaining manageable mapping complexity through automated determination.

The patent changes the parameter of block size from a fixed value to a variable that can be determined based on access requirements. The block size determining unit evaluates different parameters (access patterns, data quantities, host system requirements) and selects the optimal block size accordingly. This parameter change enables the mapping structure to adapt to varying performance requirements without fundamentally changing the overall mapping architecture.

The patent implements self-service by enabling the block size determining unit to automatically select appropriate block sizes based on data access requests without requiring manual configuration or complex external management. The system serves itself by internally evaluating access patterns and determining optimal block sizes, thereby improving data access efficiency while keeping the management process automated and reducing the burden on external control mechanisms.

The patent applies preliminary action by determining the appropriate block size in advance of actual data access operations. The block size determining unit evaluates access requirements and pre-determines the optimal block size before data transfer occurs, allowing the address mapping management to proceed smoothly with predetermined parameters rather than making complex decisions during active data operations.
