Channel-Mapped Flash Translation Layers for Large-Capacity Storage

The patent segments the L2P table into multiple smaller tables distributed across different memory channels. Each channel maintains its own L2P table, which keeps the table size manageable and fits within cache memory constraints. This segmentation allows the system to support large storage capacity while maintaining efficient cache utilization and write performance on each individual channel.

By dividing the L2P table across multiple channels, each channel handles a subset of mapping operations. This reduces the write amplification effect on each individual channel, as updates are distributed rather than concentrated in a single large table. The segmentation strategy maintains lower write amplification ratios while supporting large storage capacity.

The patent distributes L2P table entries across multiple channels, reducing the write load on each channel. This segmentation approach decreases the cumulative write amplification and stress on individual memory cells, thereby extending the overall device life while maintaining support for large storage capacity.

The patent segments the single large L2P table into multiple smaller channel-specific L2P tables. This segmentation improves cache utilization by keeping individual table sizes within cache memory limits, while the overall mapping structure remains relatively simple through the use of channel identifiers and distributed table architecture.
