Abstract: A multi-layer memory and method for performing background maintenance operations are disclosed. The memory includes a plurality of flash memory die having multiple layers, where each layer is made up of flash memory cells having a greater bit per cell storage capacity than then prior layer and each layer may have a plurality of partitions for different data types. A controller managing the flash memory die is configured to identify an idle die and determine if a layer in the die satisfies a background maintenance criterion. Upon identifying a layer satisfying the background maintenance criterion, the valid data from reclaim blocks in the layer is relocated into a relocation block in the same layer until the relocation block is filled and the background maintenance cycle ends.

Abstract: A mass storage memory system and method of operation is disclosed. The memory includes an interface adapted to receive data from a host, a plurality of flash memory die and a controller, where the controller is configured to receive a first command and read or write data synchronously across the plurality of die based on a first command, and to receive a second command and read or write data asynchronously and independently in each die based on a second command. The controller may program data in a maximum unit of programming for an individual one of the plurality of flash 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: An interactive educational device and method that provides students with activity modes in the form of instruction and exercises to be performed at a plurality of individual work stations. The invention tracks and provides information that is useful to an instructor in determining students' focus and progress. The information provided to the instructor may include, the element of the activity mode of the device the student is currently using, how long the student has been in a particular mode, and how many times the student has attempted a particular element of an activity mode. The information for each student may be updated in real time, so that at any given moment the instructor may be informed as to the student's particular activity. A “look back” for any period of time may be obtained by the instructor. The instructor receives alerts for particular events. The student may report a need for assistance, and student details may be provided to the instructor.

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. Each data file is uniquely identified in a file directory, which points to entries in a file index table (FIT) of data groups that make up the file and their physical storage locations in the memory.

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.
