The patent application (Publication Number: US20240036739A1) describes a method for data fragmentation reduction control of a memory device within a predetermined communications architecture. The method involves utilizing a memory controller to receive commands from a host device, perform discontinuity-related calculations on physical addresses, generate data fragmentation degrees, and send responses back to the host device. The memory controller communicates with the host device through a transmission interface circuit, allowing for the exchange of information related to data fragmentation reduction. The method also includes returning the data fragmentation degree to the host device for selective data fragmentation reduction based on the host device's determination result.

Furthermore, the patent application details the structure of the memory controller within the memory device, which includes a processing circuit for controlling host commands and a transmission interface circuit for communication with the host device. The memory device, comprising a non-volatile memory and the memory controller, is designed to store information and control operations efficiently. Additionally, the patent application extends to an electronic device incorporating the memory device, a host device with a processor and power supply circuit, and a computer-readable medium storing program code for executing the data fragmentation reduction control method. Overall, the method and system described in the patent application aim to enhance data fragmentation reduction in memory devices through efficient communication and calculation processes between the memory controller and host device.
