OPERATING METHOD FOR USER SYSTEM INCLUDING HOST AND MEMORY SYSTEM

摘要

An operating method of a user system having a host and a memory system, the memory system having first and second storage devices, includes deleting a first original file stored in the first storage device, using the host; generating, at the host, a comparison result by performing a comparison operation based on first delete information of the first original file and a mapping table; sending converted delete information from the host to the memory system when the comparison result indicates that a first copied file is stored in the second storage device, the first copied file being a copy of the first original file; and setting a page of the second storage device, in which the first copied file is stored, to an invalid page based on the converted delete information, using the memory system. The host recognizes the first storage device as a main device of the memory system.

1. An operating method of a user system which includes a host and a memory system, the memory system having first and second storage devices, comprising:
deleting a first original file stored in the first storage device, using the host; generating, at the host, a comparison result by performing a comparison operation based on first delete information of the first original file and a mapping table; sending converted delete information from the host to the memory system when the comparison result indicates that a first copied file is stored in the second storage device, the first copied file being a copy of the first original file; and setting a page of the second storage device, in which the first copied file is stored, to an invalid page based on the converted delete information, using the memory system, wherein the host recognizes the first storage device as a main device of the memory system, and wherein the second storage device has an erase-before-write characteristic.
