MEMORY SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240303188 titled 'MEMORY SYSTEM
The memory system described in the patent application consists of a nonvolatile memory and a controller. The controller maintains an address mapping table that links logical addresses to physical addresses of the nonvolatile memory in units of physical regions with a predetermined size. During a write operation, the controller compresses the write data into a compressed format, determines a physical address range for the compressed data, writes the compressed data into the specified range, and updates the address mapping table with second mapping information that includes the logical address of the write data, an offset specification, and the size of the compressed data.
- The memory system includes a nonvolatile memory and a controller.
- The controller maintains an address mapping table linking logical addresses to physical addresses in predetermined physical regions.
- During a write operation, the controller compresses write data, determines a physical address range, and updates the address mapping table with second mapping information.
- The second mapping information includes the logical address, an offset specification, and the size of the compressed write data.
- This system optimizes memory usage and improves data storage efficiency.
Potential Applications: - Data storage systems - Embedded systems - IoT devices
Problems Solved: - Efficient memory management - Improved data storage capacity - Enhanced write operation performance
Benefits: - Increased data storage efficiency - Optimized memory usage - Improved write operation speed
Commercial Applications: Title: "Enhanced Memory System for Improved Data Storage" This technology can be used in various commercial applications such as data centers, IoT devices, and embedded systems to enhance data storage efficiency and optimize memory usage, leading to improved performance and cost savings.

Original Abstract Submitted
a memory system includes a nonvolatile memory and a controller. the controller is configured to maintain an address mapping table including first mapping information indicating correspondence between logical addresses and physical addresses of the nonvolatile memory in units of physical regions each having a predetermined size. the controller, during a write operation compresses write data of the predetermined size into a compressed write data, determines a physical address range in which the compressed write data is to be written, writes the compressed write data into the physical address range and also second mapping information into an area in one or more physical regions spanned by the physical address range, and updates the address mapping table. the second mapping information indicates a logical address of the write data, an information capable of specifying an offset, and a size of the compressed write data.
