Abstract: A communication method of an application processor includes generating a plurality of files; generating a file set channel by transmitting a first pattern of input/output (I/O) requests to a storage device, the I/O requests being I/O requests corresponding to files from among the plurality of files; and transmitting first bit data to the storage device via the file set channel, the first bit data being transmitted using file set signaling, the file set signaling including a second pattern of I/O requests corresponding to first files from among the plurality of files such that each file in the plurality of files represents a bit of the first bit data.

Abstract: 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.

Abstract translation: 一种具有主机和存储器系统的用户系统的操作方法，所述存储器系统具有第一和第二存储设备，包括使用所述主机删除存储在所述第一存储设备中的第一原始文件; 通过基于第一原始文件的第一删除信息和映射表执行比较操作，在主机处产生比较结果; 当比较结果指示第一复制文件存储在第二存储装置中时，将转换的删除信息从主机发送到存储器系统，第一复制文件是第一原始文件的副本; 以及使用所述存储器系统，将基于所转换的删除信息将存储有所述第一复制文件的所述第二存储设备的页面设置为无效页面。 主机将第一存储设备识别为存储器系统的主要设备。
