摘要： A biometric-based security circuit in which the user database, processor, and biometric map generation functions are all located on the same integrated circuit whose secure contents are inaccessible from external to the integrated circuit. Biometric data, such as a fingerprint, retina scan, or voiceprint, is taken from a user requesting access to restricted resources. The biometric data is transferred into the integrated circuit, where it is converted to a biometric map and compared with a database of biometric maps stored in a non-volatile memory in the integrated circuit. The stored maps represent pre-authorized users, and a match triggers the security circuit to send a signal to a host processor authorizing the host processor to permit the requesting user access to the restricted resources. The integrated circuit essentially serves as a write-only memory for the secure data, because the secure data and security functions in the integrated circuit are not directly accessible through any pin or port, and therefore cannot be read or monitored through a dedicated security attack. A second non-volatile memory, accessible from external to the integrated circuit, can also be provided in the integrated circuit for holding non-secure data. This second memory has its own interface port, and is isolated from the security-related functions and memory so that secure and non-secure functions are physically isolated from each other and cannot be modified to overcome that isolation.

摘要： A method of storing data in a nonvolatile memory includes the step of receiving the data to be stored. A storage structure is selected for the data according to the relative size (z) of the data with respect to a plurality of thresholds including: a minimum number of instances (m), a maximum single instance size (s*g), and an allocation granularity (g). The data is then stored in the selected structure within the nonvolatile memory. If z is less than a first threshold, the data is stored within a multiple instance object structure. If z is less than a second threshold, the data is stored as a single instance object. If z exceeds the second threshold, the data is fragmented. The fragmented data can then be stored among the plurality of blocks of nonvolatile memory. If the number of fragments is less than a maximum sequence table size, then a sequence table indicative of the order and the locations of the data fragments is stored in the nonvolatile memory. If the number of data fragments exceeds the maximum sequence table size, then a plurality of sequence table fragments and a group table are stored in the nonvolatile memory. The group table indicates the order and the location of the sequence table fragments which in turn indicate the order and the location of the data fragments within the nonvolatile memory.

摘要： Methods of allocating, writing, reading, de-allocating, re-allocating, and reclaiming space within a nonvolatile memory having a bifurcated storage architecture are described. A method of reliably re-allocating a first object includes the step of storing a location of a first object in a first data structure. A location of the first data structure is stored in a second data structure. A duplicate of the first object is formed by initiating a copy of the first object. An erase of the first object is initiated. A write of a second object to the location of the first object is then initiated. The duplicate object is invalidated. The status of copying, erasing, and writing is tracked. The copy status, erase status, write status, and a restoration status are used to determine a recovery state upon initialization of the nonvolatile memory. The duplicate object is invalidated , if the writing status indicates that the writing of the second object has been completed. The first object is erased, if a restoration status indicates copying of the duplicate object was initiated but not completed. The erasing of the first object is completed, if the erase status indicates that erasure of the first object is not completed. A restoration of the duplicate object to the location of the first object is initiated, if the copying status indicates that copying of the first object was completed. The copying of the duplicate object is tracked as a restoration status.

摘要： Methods of allocating, writing, reading, de-allocating, re-allocating, and reclaiming space within a nonvolatile memory having a bifurcated storage architecture are described. In one embodiment, a method of reliably re-allocating a first object stored within a block erasable nonvolatile memory includes the step of allocating space for a second object. A write of the second object is initiated and the writing of the second object is tracked. In another embodiment, a method of re-allocating a first object stored within a block erasable nonvolatile memory includes the step of invalidating the first object, if the first object has an unreliable type of recovery level. Space is allocated for the second object. A write of the second object is initiated and the writing of the second object is tracked. In another embodiment, a method of reliably re-allocating a first object stored within the block erasable nonvolatile memory includes the step of allocating space for the second object. A write of the second object is initiated and the writing of the second object is tracked. The first object is invalidated after completion of writing the second object, if the first object has a reliable type of recovery. In one embodiment, the first object resides within a first portion of nonvolatile memory and the instructions for performing the described methods reside in a second portion of nonvolatile memory. The first and second portions can reside within a same nonvolatile memory such as a symmetrically blocked flash electrically erasable programmable read only memory.

摘要： A method of cleaning-up a solid state memory disk is described. Clean-up begins with the selection of a focus block for clean-up. Next, on a sector-by-sector basis, memory is allocated within a destination block to store valid sectors of user data. User data is then copied into the destination block on a sector-by-sector basis. Afterward, the focus block is erased, converting dirty sectors into free memory without loss of valid sectors of data.

摘要： A method for reliably storing management data in a flash EEPROM memory array, which array is divided into a plurality of individually-erasable blocks of memory cells and in which each of the blocks of memory cells has stored thereon data regarding management of the array during a cleanup process in which valid data stored in a first block is written to another block of the array, and then the first block is erased. The process includes the steps of storing data regarding management of the array from the first block in random access memory and, in an enhanced process, on another block before erasure of the first block. The data may then be rewritten to the first block after the erase. With the enhanced process, a special identification is provided to the data regarding the management of the array stored on another block which is outside the normal identification range for the host computer so that the specially identified data is not lost during a power loss during an erase process and may be detected after power is restored to the system.

摘要： Methods of allocating, writing, reading, de-allocating, re-allocating, and reclaiming space within a nonvolatile memory having a bifurcated storage architecture are described. A method of storing an object within a managed object space of the nonvolatile memory includes the step of determining an object class for the object. Objects of a first class are stored contiguously proceeding from a first end towards a second end of the managed object space to form a first class of space. Objects of a second class are stored contiguously proceeding from the second end towards the first end of managed object space to form a second class of space. A header identifying the object is stored at a bottom of the first class of space. The object is stored at a selected one of the bottom of the first class of space and a bottom of the second class of space in accordance with the object class.
