MEMORY SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18581505 titled 'MEMORY SYSTEM
The memory system described in the patent application involves a nonvolatile memory with blocks containing physical memory areas, and a memory controller that divides a logical address space into multiple banks, associating each bank with a block.
- The memory controller scans a portion of a table to find the physical address corresponding to a physical memory area with valid data, then reads and writes this data in different blocks associated with the same bank.
- This process allows for efficient data retrieval and storage within the memory system.
- By associating blocks with specific banks, the memory controller can optimize data access and management.
- The technology enables faster and more organized data processing in nonvolatile memory systems.
- This innovation enhances the performance and reliability of memory systems by streamlining data operations.
Potential Applications: - This technology can be applied in various storage devices such as solid-state drives and memory cards. - It can also be used in embedded systems, servers, and other computing devices that require efficient memory management.
Problems Solved: - Improves data access speed and organization in nonvolatile memory systems. - Enhances the reliability and performance of memory storage devices. - Optimizes data management processes in computing systems.
Benefits: - Faster data retrieval and storage. - Improved efficiency in memory operations. - Enhanced reliability and performance of memory systems.
Commercial Applications: Title: "Optimized Memory Management Technology for Enhanced Data Processing" This technology can be utilized in the development of high-performance storage devices for consumer electronics, data centers, and industrial applications.

Original Abstract Submitted
According to one embodiment, a memory system includes: a nonvolatile memory including blocks each of which includes physical memory areas; and a memory controller dividing a logical address space into a plurality of banks and associating a block with each of the plurality of banks. The memory controller is configured to: selectively scan a portion related to a first bank among the plurality of banks in a table in which a physical address corresponding to a physical memory area in which valid data is stored is mapped on the logical address space; detect a first physical address corresponding to a first physical memory area in a first block associated with the first bank as a result of the scan; read first valid data stored in the first block based on the first physical address; and write the first valid data in a second block associated with the first bank.
