Abstract

A control method of a storage device may include the steps of determining, by a storage device controller of the storage device, whether the storage device has to move internal data; deciding, by the storage device controller, a data movement allocation ratio based on at least some of internal data movement requests and the number of free pages in the storage device, when it is determined that the storage device has to move internal data; and allocating, by the storage device controller, one or more programming times to complete a first data number of internal data movement operations corresponding to at least some of the internal data movement requests and a second data number of host data write operations, such that the ratio of the first and second data numbers coincides with the data movement allocation ratio.
