    Abstract: A method for managing data in a storage device includes: receiving a logical page from a host and calculating an actual time stamp of the logical page; finding a block of the storage device in which the logical page is stored and detecting a time stamp of the block and a page offset of the logical page stored in the block; calculating an approximate time stamp of the logical page stored in the block using the time stamp of the block and the page offset; and determining that the logical page is in a first state if the difference between the actual time stamp and the approximate time stamp is smaller than a threshold value, and determining that the logical page is in a second state different from the first state if the difference between the actual time stamp and the approximate time stamp is larger than the threshold value.

    Abstract translation: 用于管理存储设备中的数据的方法包括：从主机接收逻辑页面并计算逻辑页面的实际时间戳; 找到其中存储有逻辑页面的存储设备的块，并检测块的时间戳和存储在块中的逻辑页的页偏移; 使用块的时间戳和页面偏移来计算存储在块中的逻辑页面的近似时间戳; 以及如果所述实际时间标记和所述近似时间戳之间的差小于阈值，则确定所述逻辑页面处于第一状态，并且如果所述差异在所述第一状态之后确定所述逻辑页面处于与所述第一状态不同的第二状态 在实际时间戳和近似时间戳之间大于阈值。

    Abstract: A computing system includes a host and a storage device. The host includes a central processing unit (CPU) and a first volatile memory device. The storage device includes a second volatile memory device and a nonvolatile memory device. The CPU uses the first volatile memory device and the second volatile memory device as a main memory to store temporary data used for operation of the CPU. The CPU determines a swap-out page to be swapped-out of first pages stored in the first volatile memory device, determines a swap-in page to be swapped-in of second pages stored in the second volatile memory device, and exchanges the swapped-out page and the swapped-in page.
