==METHOD FOR MANAGING NAMESPACES IN A STORAGE DEVICE AND STORAGE DEVICE EMPLOYING THE SAME - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240086092 titled 'METHOD FOR MANAGING NAMESPACES IN A STORAGE DEVICE AND STORAGE DEVICE EMPLOYING THE SAME

==Simplified Explanation==

The patent application describes a storage device that supports multiple namespaces by utilizing over-provisioning chunks from a pool to accommodate unaligned chunks in the namespaces. The controller in the storage device manages the allocation of memory for each namespace efficiently.

* The storage device includes a memory and a controller with a host interface layer and a flash translation layer.
* The controller selects over-provisioning chunks and separate chunks to allocate memory for namespaces.
* The controller receives commands to utilize memory for specific namespaces, including unaligned chunks, and assigns over-provisioning chunks for this purpose.
* The number of over-provisioning chunks available is limited, so they are used strategically for unaligned chunks in namespaces.

== Potential Applications ==
This technology can be applied in:
* Solid-state drives
* Data centers
* Cloud storage solutions

== Problems Solved ==
* Efficient memory allocation for multiple namespaces
* Optimized use of over-provisioning chunks
* Improved performance and reliability of storage devices

== Benefits ==
* Enhanced storage device performance
* Increased reliability and longevity
* Better utilization of memory resources

== Potential Commercial Applications ==
Optimizing Memory Allocation in Storage Devices for Improved Performance

== Possible Prior Art ==
One possible prior art could be the use of over-provisioning in storage devices to enhance performance and reliability.

== Unanswered Questions ==

=== How does this technology impact the cost of storage devices? ===
The article does not address the potential cost implications of implementing this technology in storage devices.

=== What are the specific performance improvements seen with this technology? ===
The article does not provide detailed information on the performance enhancements achieved with the utilization of over-provisioning chunks for unaligned chunks in namespaces.


==Original Abstract Submitted==

a provided a storage device configured to support a number of namespaces. the storage device includes a memory and a controller coupled to the memory. the controller includes a host interface layer and a flash translation layer configured to report to the host interface layer a first over-provisioning chunk from an over-provisioning pool and a first chunk separate from the over-provisioning pool. the controller is configured to receive a command at the host interface layer to utilize a portion of the memory for a first namespace from among the number of namespaces and the first namespace includes an unaligned chunk. the controller is configured to utilize the first over-provisioning chunk as the unaligned chunk of the first namespace. a number of over-provisioning chunks to be utilized as unaligned chunks is less than the number of namespaces.
