ABSTRACT:
A flash storage device having improved write performance is provided. The device includes a storage block having a plurality of physical pages and a controller configured to allocate subsets of the plurality of physical pages to a plurality of logical addresses, respectively, and to write data to the plurality of physical pages. Each of the subsets of physical pages includes more than one physical page. Upon receiving a first write request for one of the logical addresses, data from the first write request is written to a first physical page of the physical pages allocated to the logical address. Upon receiving a second write request for one of the logical address, the data from the second write request is written to a second physical page allocated to the logical address and the first physical page allocated to the logical address is invalidated.
