Abstract: A mass storage memory system and method of operation are disclosed. The memory system includes an interface adapted to receive data from a host system, a plurality of memory die and a controller, where the controller is configured to read or write data synchronously across a plurality of die connected to different channels based on a first command, and to read or write data asynchronously and independently in different die in the same channel based on a second command. The controller may program data in a maximum unit of programming for a single memory die. The controller may be a plurality of controllers each configured to select which die of an exclusive subset of die to write data based on characteristics of the die in the subset. The plurality of die may be multi-layer, and multi-partition per layer, flash memory die.

Abstract: A multi-layer memory and method for operation is disclosed. The memory includes multiple layers, where each layer includes flash memory cells having a greater bit per cell capacity than the prior layer and each layer may include a plurality of partitions having blocks exclusively associated with a particular data type. The method may include directing host data directly into a particular partition of a particular layer of the multi-layer memory upon receipt depending on a type of the data. The method may also include copying data within the same partition in a respective layer in a data relocation operation to generate more free blocks of memory so that data preferably stays within each layer and in the same partition, as well as transferring data from one layer to the next higher bit per cell layer within a same partition when layer transfer criteria are met.

Abstract: A multi-later memory and method for operation is disclosed. The memory includes three or more layers, where each layer is made up of flash memory cells having a greater bit per cell storage capacity than then prior layer. The method may include the steps of directing host data directly into a first or second layer of the multi-layer memory upon receipt depending on a condition of the data. The method may also include copying data within a respective layer in a data relocation operation to generate more free blocks of memory so that data preferably stays within each layer, as well as transferring data from one layer to the next higher bit per cell layer when layer transfer criteria are met.

Abstract: Data files are assigned addresses within one or more logical blocks of a continuous logical address space interface (LBA interface) of a usual type of flash memory system with physical memory cell blocks. This assignment may be done by the host device which typically, but not necessarily, generates the data files. The number of logical blocks containing data of any one file is controlled in a manner that reduces the amount of fragmentation of file data within the physical memory blocks, thereby to maintain good memory performance. The host may configure the logical blocks of the address space in response to learning the physical characteristics of a memory to which it is connected.

Abstract: Host system data files are written directly to a large erase block flash memory system with a unique identification of each file and offsets of data within the file but without the use of any intermediate logical addresses or a virtual address space for the memory. Directory information of where the files are stored in the memory is maintained within the memory system by its controller, rather than by the host. A type of memory block is selected to receive additional data of a file that depends upon the types of blocks into which data of the file have already been written. Blocks containing data are selected for reclaiming any unused capacity therefrom by a process that selects blocks in order starting with those containing the least amount of valid data.

Abstract: Systems and methods for allocating blocks at a reprogrammable non-volatile mass storage system are disclosed. Generally, a controller identifies a group of data to be written to a block at the mass storage system, and allocates one of a new block or a partial block to the identified group of data based on whether a total unprogrammed capacity in partial blocks of the mass storage system exceeds an amount of valid data in obsolete blocks of the mass storage system. In one implementation, the identifier group of data may be associated with a single file.

Abstract: A method and system for storage address re-mapping is disclosed. The method includes allocating logical addresses in blocks of clusters and re-mapping logical addresses into storage address space, where short runs of data dispersed in logical address space are mapped in a contiguous manner into blocks in storage address space. Valid data is flushed from blocks having both valid and obsolete data to make new blocks available for receiving data when an available number of new blocks falls below a desired threshold. The system includes a host file system, processor executable instructions residing on a host separately from the host file system or residing on a flash memory device such as an embedded solid state disk, or a backend memory manager of the flash memory device that is configured to map data from a logical address space to complete blocks in storage address space in a contiguous manner.
