Abstract
An information processing apparatus determines, when data is written to a semiconductor storage including a plurality of flash memories, whether or not the data to be written is specific data (data associated with the complete erasure) for which it is set that unnecessary data relating to the data is made to be erasable so that the unnecessary data does not remain in the semiconductor storage. In a case where it is determined that the data to be written is not the specific data, the information processing apparatus performs data write processing in a state where an interleave is enabled. Meanwhile, in a case where it is determined that the data to be written is the specific data, the information processing apparatus performs data write processing in a state where the interleave is disabled.
