STORAGE CONTROLLER AND AN OPERATION METHOD OF THE STORAGE CONTROLLER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18105920 titled 'STORAGE CONTROLLER AND AN OPERATION METHOD OF THE STORAGE CONTROLLER
Simplified Explanation
The patent application describes a storage controller that manages nonvolatile memories using two flash translation layers (FTLs). The FTLs handle different logical addresses and communicate with the memories through separate channels. The first FTL manages the first and fourth requests, while the second FTL manages the second and third requests.
- The storage controller has a host interface circuit that receives requests for different logical addresses.
- It also has a memory interface circuit that communicates with nonvolatile memories through two separate channels.
- The first FTL manages the first and fourth requests, and the second FTL manages the second and third requests.
- The logical addresses are arranged in a specific order, with the value of the first address being smaller than the value of the second address, and the value of the third address being smaller than the value of the fourth address.
Potential applications of this technology:
- Data storage systems: The storage controller can be used in various data storage systems, such as solid-state drives (SSDs) or memory cards.
- Cloud storage: The technology can be implemented in cloud storage infrastructure to improve performance and efficiency.
Problems solved by this technology:
- Efficient memory management: By using two FTLs and separate channels, the storage controller can optimize memory access and improve overall performance.
- Logical address management: The arrangement of logical addresses ensures efficient data organization and retrieval.
Benefits of this technology:
- Improved performance: The use of two FTLs and separate channels allows for parallel processing and faster data access.
- Enhanced memory utilization: The storage controller efficiently manages logical addresses, maximizing the utilization of nonvolatile memories.
Original Abstract Submitted
A storage controller including: a host interface circuit receiving first, second, third and fourth requests corresponding to first, second, third and fourth logical addresses; a memory interface circuit communicating with first nonvolatile memories through a first channel and second nonvolatile memories through a second channel; a first flash translation layer configured to manage the first nonvolatile memories; and a second flash translation layer configured to manage the second nonvolatile memories, the first flash translation layer outputs commands corresponding to the first and fourth requests through the first channel, and the second flash translation layer outputs commands respectively corresponding to the second and third requests through the second channel, and a value of the first logical address is smaller than a value of the second logical address, and a value of the third logical address is smaller than a value of the fourth logical address.
