STORAGE DEVICE PROVIDING DIRECT MEMORY ACCESS, COMPUTING SYSTEM INCLUDING THE SAME, AND OPERATING METHOD OF THE STORAGE DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240320173 titled 'STORAGE DEVICE PROVIDING DIRECT MEMORY ACCESS, COMPUTING SYSTEM INCLUDING THE SAME, AND OPERATING METHOD OF THE STORAGE DEVICE
The storage device described in the patent application includes various components such as a buffer memory, two direct memory access (DMA) circuits, an address translation circuit, and a buffer controller.
- The first DMA circuit transfers data between a host and the buffer memory, providing a first virtual address.
- The second DMA circuit transfers data between a non-volatile memory and the buffer memory, providing a second virtual address.
- The address translation circuit translates virtual addresses into physical addresses within a specified reference range.
- The buffer controller accesses the buffer memory based on the physical address of the virtual address that is excluded from translation.
Potential Applications: - This technology could be used in high-speed data storage systems. - It may find applications in cloud computing environments where efficient data transfer is crucial.
Problems Solved: - Efficient data transfer between different memory components. - Simplified address translation process for improved performance.
Benefits: - Faster data transfer speeds. - Reduced latency in accessing stored data. - Improved overall system performance.
Commercial Applications: Title: Enhanced Data Storage System for High-Performance Computing This technology could be utilized in servers, data centers, and other high-performance computing environments to enhance data transfer speeds and overall system efficiency.
Questions about the technology: 1. How does the address translation circuit improve data access speeds? 2. What are the potential cost savings associated with implementing this storage device in a data center environment?
Original Abstract Submitted
a storage device includes a buffer memory, a first direct memory access (dma) circuit configured to provide data from a host to the buffer memory or data stored in the buffer memory to the host and output a first virtual address, a second dma circuit configured to provide data read from a non-volatile memory to the buffer memory or the data stored in the buffer memory to the non-volatile memory and output a second virtual address, an address translation circuit configured to translate the first or second virtual address into a physical address when the first or second virtual address is included in a reference range and skip the translation operation when the first or second virtual address is excluded in the reference range. a buffer controller is configured to access the buffer memory based on the physical address of the first or second virtual address that is excluded.
