GARBAGE COLLECTION - AUTOMATIC DATA PLACEMENT - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18135729 Titled 'GARBAGE COLLECTION - AUTOMATIC DATA PLACEMENT'
Simplified Explanation
The abstract describes a Solid State Drive (SSD) that uses flash memory to store data. The SSD has a controller that manages the reading and writing of data to the flash memory. It also includes a feature called automatic stream detection logic, which helps in selecting a stream identifier based on the attributes of the data. Additionally, the SSD has a garbage collection logic that selects an erase block and moves valid data from that block to a second block, based on the stream ID determined by the automatic stream detection logic. The stream ID is determined after the garbage collection logic has already selected the erase block for garbage collection.
Original Abstract Submitted
A Solid State Drive (SSD) is disclosed. The SSD may include flash memory to store data. An SSD controller may manage reading and writing data to the flash memory. The SSD may include an automatic stream detection logic to select a stream identifier responsive to attributes of data. A garbage collection logic may select an erase block and program valid data in the erase block into a second block responsive to a stream ID determined the automatic stream detection logic. The stream ID may be determined after the garbage collection logic has selected the erase block for garbage collection.
