A method and system for page preloading using a control flow are provided. The method includes extracting preload page information from one or more pages in a first program code, and generating a second program code including the first program code and the extracted preload page information. The second program code is stored in non-volatile memory. When loading a page from the second program code stored in the non-volatile memory into main memory, preloading one or more pages from the non-volatile memory based on the preload page information stored in the loaded page.

Method and system for preloading page using control flow

A device driver including a flash memory file system and method thereof and a flash memory device and method thereof are provided. The example device driver may include a flash memory file system configured to receive data scheduled to be written into the flash memory device, the flash memory file system selecting one of a first data storage area and a second data storage area within the flash memory device to write the received data to based upon an expected frequency of updating for the received data, the first data storage area configured to store data which is expected to be updated more often than the second data storage area. The example flash memory device may include a first data storage area configured to store first data, the first data having a first expected frequency for updating and a second data storage area configured to store second data, the second data having a second expected frequency of updating, the first expected frequency being higher than the second expected frequency.

Device driver including a flash memory file system and method thereof and a flash memory device and method thereof

Disclosed is a semiconductor memory system and wear-leveling method thereof. The semiconductor memory system is comprised of a nonvolatile memory including a plurality of logic blocks each of which is divided into a plurality of entries, a file system detecting a type of data to be stored and allocating the logic block or the entry for storing the data in accordance with the data type, and a translation layer leveling wearing degrees over the logic blocks or the entries in accordance with the data type.
