Electronic device storing mapping information and method of operating the same

Abstract

Disclosed is a method of operating an electronic device which includes a first storage device, a second storage device, and a host device. The method includes providing a first request indicating a memory operation of target data to the first storage device, providing a second request indicating a redirection of the memory operation to the second storage device based on the first request, performing the memory operation based on the second request, providing the first storage device with a first completion response indicating that the memory operation is performed, and providing a second completion response to the host device based on the first completion response. The first storage device stores first mapping information of a logical block address (LBA) of the target data and a physical block address (PBA) indicating a physical block of the second storage device, in which the target data are stored.
