Abstract: A non-volatile solid state memory-based mass storage device having at least one non-volatile memory component and methods of operating the storage device. In one aspect of the invention, the one or more memory components define a memory space partitioned into user memory and over-provisioning pools based on a P/E cycle count stored in a block information record. The storage device transfers the P/E cycle count of erased blocks to a host and the host stores the P/E cycle count in a content addressable memory. During a host write to the storage device, the host issues a low P/E cycle count number as a primary address to the content addressable memory, which returns available block addresses of blocks within the over-provisioning pool as a first dimension in a multidimensional address space. Changed files are preferably updated in append mode and the previous version can be maintained for version control.

The individual zones can be the same or different among the parallel control channels.

Abstract: A NAND-based flash memory device and a method of its operation that extends the life of the device by reducing the number of unnecessary write cycles to the device. The memory device includes blocks, pages contained by each of the blocks, and a page abstraction layer containing a look-up table for translating logical page numbers into physical page numbers. A certain number of the pages in at least one of the blocks is preferably reserved so as not to be used in default data storage mode but instead used to shuffle data within the at least one block using a dynamic page address scheme, whereby data are dynamically moved from one page to an empty page in the same block using dynamic page mapping.

Abstract: Non-volatile solid-state memory-based storage devices and methods of operating the storage devices to have low initial error rates. The storage devices and methods use bit error rate comparison of duplicate writes to one or more non-volatile memory devices. The data set with a lower bit error rate as determined during verification is maintained, whereas data sets with higher bit error rates are discarded. A threshold of bit error rates can be used to trigger the duplication of data for bit error comparison.
