Memory controller, flash memory system having memory controller and method for controlling flash memory device

Abstract

A memory controller includes decision means responsive to a request to write user data issued by a host computer for determining whether progressive data writing for writing user data to a target page designated by a host address is possible, and write means responsive to an affirmative determination by the decision means for writing user data to the target page without performing an inter-block data transfer. Thus, a series of data write operations for completing data writing can be performed at high speed because the frequency of inter-block data transfers is low.
