TECHNIQUES FOR LOGICAL-TO-PHYSICAL INFORMATION COMPRESSION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18612896 titled 'TECHNIQUES FOR LOGICAL-TO-PHYSICAL INFORMATION COMPRESSION

Simplified Explanation

The patent application describes methods, systems, and devices for compressing logical-to-physical information in a memory system. This compression technique allows for expanding the quantity of physical addresses mapped by the logical-to-physical mapping.

The memory system compresses consecutive entries of an uncompressed logical-to-physical mapping into a single entry.
The compressed entry includes a starting physical address of the consecutive physical addresses and an indication of the starting logical address.
To identify a physical address within the compressed entry, the memory system determines an offset between the logical address and the starting physical address using the indication.

Key Features and Innovation

Compression of logical-to-physical information in a memory system.
Expansion of the quantity of physical addresses mapped by the logical-to-physical mapping.

Original Abstract Submitted

Methods, systems, and devices for techniques for logical-to-physical information compression are described. In some cases, a memory system may compress a logical-to-physical (L2P) mapping to expand the quantity of physical addresses mapped by the L2P mapping. For example, if a set of consecutive entries of an uncompressed L2P mapping includes consecutive physical addresses, the memory system may compress the consecutive entries into a single entry which includes a starting physical address of the consecutive physical addresses. Additionally, the memory system may include an indication of a starting logical address corresponding to the starting physical address in the compressed entry. To identify a physical address within the compressed entry, the memory system may determine an offset between a logical address corresponding to the physical address and the starting physical address using the indication, and may apply the offset to the starting physical address to determine the physical address.
