This abstract first appeared for US patent application 17949132 titled 'Dynamic And Shared CMB And HMB Allocation
Simplified Explanation
The abstract describes a data storage device with a controller that can allocate either a controller memory buffer (CMB) or a host memory buffer (HMB) based on latency and performance tradeoffs.
- The controller of the data storage device includes a controller memory buffer (CMB) and a host memory buffer (HMB) that are associated as a single buffer pool.
- The controller can allocate either a CMB buffer or a HMB buffer based on the tradeoff between latency and performance.
- By leveraging both the CMB and HMB to store data, the overall performance of the data storage device can be improved.
Potential Applications
This technology could be applied in:
- Solid-state drives
- Cloud storage systems
- Data centers
Problems Solved
This technology addresses:
- Latency issues in data storage devices

Possible Prior Art
One possible prior art for this technology could be the use of hybrid memory systems in data storage devices.
What are the specific technical details of the controller memory buffer (CMB) and host memory buffer (HMB) in the data storage device?
The abstract mentions that the controller memory buffer (CMB) and host memory buffer (HMB) are associated as a single buffer pool. However, it does not provide specific technical details about the size, structure, or operation of these buffers.
How does the controller determine whether to allocate a CMB buffer or a HMB buffer based on the tradeoff between latency and performance?
The abstract states that the controller can allocate either a CMB buffer or a HMB buffer based on a tradeoff between latency and performance. However, it does not explain the specific criteria or algorithms used by the controller to make this decision.
Original Abstract Submitted
A data storage device includes a controller. The controller includes a controller memory buffer (CMB). The controller is configured to associate both the CMB and a host memory buffer (HMB) of a host device as a single buffer pool with a plurality of CMB buffers and a plurality of HMB buffers. The controller is further configured to allocate either a CMB buffer or a HMB buffer based on a tradeoff between latency and performance between using the CMB or using the HMB to store data. By leveraging the benefits of both the CMB and the HMB to store data, the overall performance of the data storage device may be improved.
