Abstract
During a programming data transfer process in a non-volatile storage system, recording units of data are transferred from a host to a memory device, such as a memory card. For each recording unit, pages of data are arranged in an order such that a page which takes longer to write to a memory array of the memory device is provided before a page which takes less time to write. Overall programming time for the recording unit is reduced since a greater degree of parallel processing occurs. While the page which takes longer to program is being programmed to the memory array, the page which takes less time to program is being transferred to the memory device. After programming is completed, the memory device signals the host to transfer a next recording unit. The pages of data may include lower, middle and upper pages.
