OPERATION METHOD OF HOST CONFIGURED TO COMMUNICATE WITH STORAGE DEVICES AND MEMORY DEVICES, AND SYSTEM INCLUDING STORAGE DEVICES AND MEMORY DEVICES - A simplified explanation of the abstract

This abstract first appeared for US patent application 18130650 titled 'OPERATION METHOD OF HOST CONFIGURED TO COMMUNICATE WITH STORAGE DEVICES AND MEMORY DEVICES, AND SYSTEM INCLUDING STORAGE DEVICES AND MEMORY DEVICES

Simplified Explanation

The patent application describes a system that includes multiple storage devices and a memory device connected through a communication interface called Compute Express Link (CXL). A CXL switch is used to manage the communication between the storage devices and the memory device.

  • The system includes a first CXL storage device, a second CXL storage device, and a first CXL memory device.
  • These devices are connected to a CXL switch through a CXL interface.
  • The CXL switch is responsible for managing the communication between the storage devices and the memory device.
  • The first CXL memory device stores map data of both the first and second CXL storage devices.
  • The first CXL storage device exchanges a portion of its map data with the first CXL memory device through the CXL switch.
  • Similarly, the second CXL storage device exchanges a portion of its map data with the first CXL memory device through the CXL switch.


Original Abstract Submitted

A system includes a first compute express link (CXL) storage device, a second CXL storage device, a first CXL memory device, and a CXL switch connected to the first CXL storage device, the second CXL storage device and the first CXL memory device through a CXL interface, the CXL switch configured to arbitrate communications between the first CXL storage device and the second CXL storage device, and the first CXL memory device. The first CXL memory device is configured to store first map data of the first CXL storage device and second map data of the second CXL storage device, the first CXL storage device is configured to exchange at least a portion of the first map data with the first CXL memory device through the CXL switch, and the second CXL storage device is configured to exchange at least a portion of the second map data with the first CXL memory device through the CXL switch.
