Optimized Read-Modify-Writes During Relocation of Overlapping Logical Blocks - A simplified explanation of the abstract

This abstract first appeared for US patent application 17847078 titled 'Optimized Read-Modify-Writes During Relocation of Overlapping Logical Blocks

Simplified Explanation

The patent application describes systems and methods for performing read-modify-write operations during the relocation of overlapping logical blocks in a device memory. Here is a simplified explanation of the abstract:

The method starts by receiving a write command from a host interface.
The logical block address in the write command is translated to a physical address on the device memory.
The physical address corresponds to multiple indirection units.
If the physical address is not aligned, a read-modify-write operation is performed on one or more indirection units during the relocation process.
This is done when a relocation block has an overlapping indirection unit with the one being modified.

Potential applications of this technology:

Data storage systems: This technology can be used in storage devices such as solid-state drives (SSDs) to efficiently handle write commands and manage the relocation of logical blocks.
Cloud computing: The technology can be applied in cloud storage systems to improve the performance and reliability of data storage and retrieval operations.

Problems solved by this technology:

Efficient relocation of overlapping logical blocks: By performing read-modify-write operations during relocation, this technology ensures that data is correctly written to the new location without losing any information.
Address translation: The method translates logical block addresses to physical addresses, allowing for efficient data storage and retrieval.

Benefits of this technology:

Improved data integrity: By performing read-modify-write operations, the technology ensures that data is correctly relocated without any loss or corruption.
Enhanced performance: The method optimizes the relocation process by only performing read-modify-write operations when necessary, reducing the overall time and resources required.
Efficient use of memory: By utilizing indirection units and aligning addresses, the technology maximizes the use of device memory and improves storage efficiency.

Original Abstract Submitted

Disclosed are systems and methods for providing read-modify-writes during relocation of overlapping of logical blocks. A method includes receiving a host write command from a host interface. The method also includes translating a logical block address for the host write command to a physical address on a device memory. The physical address corresponds to a plurality of indirection units. The method also includes, in accordance with a determination that the physical address does not correspond to an aligned address, processing a read-modify-write operation for one or more indirection units of the plurality of indirection units during a relocation, in accordance with a determination that a relocation block has an overlapping indirection unit with the one or more indirection units.
