EFFICIENT L2P DRAM FOR HIGH-CAPACITY DRIVES - A simplified explanation of the abstract
This abstract first appeared for US patent application 17945586 titled 'EFFICIENT L2P DRAM FOR HIGH-CAPACITY DRIVES
Simplified Explanation
The present disclosure discusses a method to improve space efficiency in storing logical to physical (L2P) entries by splitting the physical block address (PBA) between a buffer and metadata buffer.
- Splitting PBA between buffer and metadata buffer
- Adding extra bits to metadata buffer to optimize space
- Preserving alignment and improving DRAM access
- Easily optimizing and adapting metadata buffer
Potential Applications

Original Abstract Submitted
The present disclosure generally relates to improving space efficiency when storing logical to physical (L2P) entries. Rather than writing a physical block address (PBA) spanning multiple entries, the PBA is split between a first portion stored in the buffer with the remaining bits of the PBA added to the metadata buffer. The metadata buffer is sub-optimal due to the small size of the metadata relative to the entry and therefore, adding extra bits to the metadata buffer will make the metadata buffer more optimal. In this scheme, the alignment is preserved, the system becomes more optimal in terms of DRAM access, and the metadata buffer can be easily optimized and adapted.
