STORAGE DEVICE, OPERATION METHOD OF STORAGE DEVICE, AND STORAGE SYSTEM USING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18492762 titled 'STORAGE DEVICE, OPERATION METHOD OF STORAGE DEVICE, AND STORAGE SYSTEM USING THE SAME
Simplified Explanation
The abstract describes a storage device with a nonvolatile memory device and a storage controller that includes a multi-protocol host interface circuit. This circuit handles different types of requests from an external host, transmitting/receiving data in block units for one type of request and in smaller units for another type. A mapping cache manager manages an address translation table cache, sending requests for address translation to the external host and receiving mapping information in response.
- Storage device with nonvolatile memory and storage controller

Original Abstract Submitted
A storage device includes a nonvolatile memory device and a storage controller. The storage controller includes a multi-protocol host interface circuit that receives a first-type request including a first logical address from an external host and transmits/receives data corresponding to the first-type request with the external host by a block unit. Additionally, the multi-protocol host interface circuit receives a second-type request including a first physical address from the external host and transmits/receives data corresponding to the second-type request with the external host by a unit smaller than the block unit. A mapping cache manager manages an address translation table cache, sends an address translation request including the first physical address to the external host, and receives a response including mapping information corresponding to the first physical address from the external host.
