PERFORMING MEMORY ACCESS OPERATIONS WITH A LOGICAL-TO-PHYSICAL MAPPING TABLE WITH REDUCED SIZE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18582926 titled 'PERFORMING MEMORY ACCESS OPERATIONS WITH A LOGICAL-TO-PHYSICAL MAPPING TABLE WITH REDUCED SIZE
Simplified Explanation:
The patent application describes a data structure that maps logical addresses to physical addresses in memory. It consists of L2P table entries that point to specific locations on a non-volatile memory device, and P2L data structures that map physical addresses back to logical addresses on a volatile memory device.
Key Features and Innovation:
- L2P table entries contain block numbers and page table indexes for non-volatile memory.
- P2L data structures correspond to portions of the L2P data structure.
- Efficient mapping of logical addresses to physical addresses and vice versa.
Potential Applications: This technology can be used in various storage systems, databases, and file systems where efficient address mapping is crucial.
Problems Solved:
- Simplifies the process of translating logical addresses to physical addresses.
- Improves memory management and access efficiency.
Benefits:
- Faster data access and retrieval.
- Enhanced memory utilization.
- Streamlined address mapping processes.
Commercial Applications: Potential commercial applications include data storage solutions, database management systems, and cloud computing platforms.
Prior Art: Readers can explore prior research on logical-to-physical address mapping in memory systems and data storage technologies.
Frequently Updated Research: Stay updated on advancements in memory mapping algorithms and data structure optimizations for improved performance.
Questions about Logical-to-Physical Data Structure: 1. How does the logical-to-physical data structure improve memory access efficiency? 2. What are the key differences between L2P and P2L data structures in memory mapping?
Original Abstract Submitted
A logical-to-physical (L2P) data structure comprising a plurality of L2P table entries is maintained on the volatile memory device. Each L2P table entry comprises a block number and a page table index corresponding to the non-volatile memory device. A plurality of physical-to-logical (P2L) data structures each comprising a plurality of P2L table entries is maintained on the volatile memory device. Each of the plurality of P2L data structures corresponds to a portion of the L2P data structure.
