Title: (EN) Increasing the memory performance of flash memory devices by writing sectors simultaneously to multiple flash memory devices
Abstract: front page image
(EN)

A memory storage system of an embodiment includes a nonvolatile memory unit and memory control circuitry coupled to the memory unit. Storage locations of the memory unit are organized into one or more sub-blocks configured to store sectors of information from a host. The sectors of information can be identified by sector numbers of a predetermined order. The memory control circuitry is configured to write a sector of information to a location of a particular sub-block of a particular block. The memory control circuitry is further configured to write a sector of information to a location of a sub-block of the particular block that is other than the particular sub-block, regardless of the predetermined order of the sector numbers of the sectors of information. The memory control circuitry is further configured to write the sectors of information to the locations of the sub-blocks of the particular block substantially concurrently.
