Data storage control method and apparatus for external storage device using a plurality of flash memories

The present invention is to realize a data storage control method and apparatus for an external storage device using flash memories. The method and apparatus can eliminate the data erasure waiting time, eliminating the calculation of the erasure numbers of flash memories, elongating the life-time of the flash memories. Data is stored sequentially from a first flash memory for rewrite data to a third flash memory for rewrite data. When there is no vacant area in the third flash memory for rewrite data, a CPU instructs a first flash memory for garbage collection among the first and second flash memories for garbage collection to perform the garbage collection of the first flash memory for rewrite data. When a host computer issues a write access request, the write process is performed in the first flash memory for garbage collection with the first priority. When the garbage collection of the first flash memory for rewrite data has been completed, the garbage collection of the second flash memory for rewrite data is performed by the second flash memory for garbage collection. At the time of performing the garbage collection of the second flash memory for rewrite data, the data of the first flash memory for rewrite data is simultaneously erased. The first flash memory for garbage collection is changed into a flash memory for rewrite data by the CPU. Upon completion of the garbage collection of the second flash memory for rewrite data, the data thereof is simultaneously erased and the second flash memory for garbage collection is changed into a flash memory for rewrite data. Then, the garbage collection of the third flash memory for rewrite data is performed in the similar manner.

Method for improving deformation and permeability in high-thickness standard steel plate hot rolling process

A method for improving deformation and permeability in the high-thickness standard steel plate hot rolling process is characterized in that a uniform fast cooling device is arranged at a position close to the opening of a heavy and medium plate mill or hot strip roughing mill with the length being 5 to 15 meters and the cooling total water being 3,000 to 6,000 cubic meters per hour respectively; before rolling, the cooling device conducts asymmetrical uniform fast cooling to the upper and lower surfaces of a plate blank, a low-temperature hardened layer is formed on the surface of the plate blank, the temperature gradient of a core reaches 2 to 3 DEG C per millimeter, before the cooling returns red, the cooling device can quickly enter the mill to conduct differential temperature rolling, and plate blank core deformation is improved; the cooling device is further combined with asymmetrical rolling, while deepening the plate blank core deformation, the cooling device solves the warping problem caused by the asymmetrical rolling through the asymmetrical cooling of the upper and lower surfaces of the plate blank before rolling. For a steel ball needing two-stage control, the uniform fast cooling device can replace a middle cooling device, shortens or even eliminates the temperature waiting time of swinging steel, and improves the production efficiency.
