摘要： A non-volatile memory system is organized in physical groups of physical memory locations. Each physical group (metablock) is erasable as a unit and can be used to store a logical group of data. A memory management system allows for update of a logical group of data by allocating a metablock dedicated to recording the update data of the logical group. The update metablock records update data in the order received and has no restriction on whether the recording is in the correct logical order as originally stored (sequential) or not (chaotic). Eventually the update metablock is closed to further recording. One of several processes will take place, but will ultimately end up with a fully filled metablock in the correct order which replaces the original metablock. In the chaotic case, directory data is maintained in the non-volatile memory in a manner that is conducive to frequent updates. The system supports multiple logical groups being updated concurrently.

摘要： In the file storage system, each portion belonging to a data file is identified by its file ID and an offset along the data file, where the offset is a constant for the file and every file data portion is always kept at the same position within a memory page to be read or programmed in parallel. In this way, every time a page containing a file portion is read and copy to another page, the data in it is always page-aligned, and each bit within the file portion can always be manipulated by the same sense amplifier and same set data latches within the same memory column. In a preferred implementation, the page alignment is such that (offset within a page)=(data offset within a file) MOD (page size). Any gaps that may exist in page can be padded with any existing page-aligned valid data.

摘要： The present invention presents techniques whereby a memory system interrupts a programming process and restarts it including additional data. More specifically, when a memory system programs data into a group of cells together as programming unit, programming can begin with less than the full data content which the group can hold. In one embodiment, the present invention allows overlapped programming of upper and lower data pages, where once the memory begins programming the lower logical data page, if data is received for the upper page assigned to the same physical page, programming is interrupted and recommenced with the concurrent programming of both the upper and the loser pages. In a complimentary embodiment, when a page contains multiple sectors of data, programming of the physical page can begin when one or more, but less than all, of the sectors forming the corresponding logical page have been received, stopped and restarted to include additional sectors of the page.

摘要： Update data to a non-volatile memory may be recorded in at least two interleaving streams such as either into an update block or a scratch pad block depending on a predetermined condition. The scratch pad block is used to buffered update data that are ultimately destined for the update block. In a preferred embodiment, an index of the data stored in the scratch pad block as well that stored in the update block is saved in an unused portion of the scratch pad block every time the scratch pad block is written to.

摘要： The present invention presents a number of improvements for managing erase processes in non-volatile memory. Such memory systems typically manage the memory by logically organize the basic unit of physical erase (erase block) into composite logical groupings (meta-blocks or logical group), where an erase block generally consists of a number of sectors. When an erase command is received, the specified sectors are checked against the memory system's control data. If the specified sectors span any full logical grouping, the full logical groupings can each be treated a whole and erased according to one process (such as performing a true, physical erase), while other sectors are “logically” erased at the sector level by standard techniques.

摘要： A memory system is presented where sectors are normally stored in logically contiguous groups. As repeated writes of the same small sector group can causes a massive garbage collection (data relocation), the pattern of host access is monitored by checking the sectors' update history and control data structures' update history. When repeated access patterns are detected and then expected again, the “hot” segments are separated into specially handled, non-standard zone in the memory. The non-standard zone has a sector management that is different from the logical groups and optimized for the repeated host accesses in order to reduce the frequency and amount of garbage collection operations.

摘要： The invention describes the method for regrouping data read from multi-sector pages inside a memory chip. As a result, garbage collection operation time greatly reduces and overall system performance increases. Architectural features include the ability to selectively transfer individual data sectors of a page between on-chip registers and the ability to realign data sectors within a register.
