Storage device that determines data attributes based on continuity of address ranges

Abstract

A storage device includes a nonvolatile memory including a plurality of blocks, and a controller. The controller is configured to retain a logical address range designated by each of a plurality of write commands that were received, and upon each gap of two adjacent logical address ranges of two or more of the write commands being smaller than a first threshold and an entire length of the logical address ranges of said two or more write commands being larger than a second threshold, write data corresponding to one of said two or more write commands in one of the blocks of the nonvolatile memory, as a part of a single data group comprising data corresponding to each of said two or more write commands, such that data that do not form the single data group are not written in said one of the blocks of the nonvolatile memory.
