摘要： A digital system including flash memory, coupled to a system-on-a-chip within which a flash memory subsystem controller is embedded, is disclosed. The system-on-a- chip includes support for a standard external interface, such as a Universal Serial Bus (USB) or IEEE 1394 interface, to which a host system such as flash memory test equipment can connect. Initialization of the flash memory is effected by opening a communications channel between the host system and the embedded flash memory subsystem controller. The host system can then effect initialization of the flash memory subsystem, including formatting of the flash memory arrays, loading application programs, and the like, over the communications channel.

摘要： Data in less than all of the pages of a non-volatile memory block are updated by programming the new data in unused pages of either the same or another block. In order to prevent having to copy unchanged pages of data into the new block, or to program flags into superceded pages of data, the pages of new data are identified by the same logical address as the pages of data which they superceded and a time stamp is added to note when each page was written. When reading the data, the most recent pages of data are used and the older superceded pages of data are ignored. This technique is also applied to metablocks that include one block from each of several different units of a memory array, by directing all page updates to a single unused block in one of the units.

摘要： In a memory array having redundant columns, a scheme allows defective cells to be individually remapped to redundant cells in a redundant column. Redundant cells in one redundant column replace defective cells in multiple non-redundant columns. Remapping is done as part of initial test and configuration. Specific hardware can be used for the scheme or firmware in the memory controller can implement the scheme.

摘要： In order to maintain the integrity of data stored in a flash memory that are susceptible to being disturbed by operations in adjacent regions of the memory, disturb events cause the data to be read, corrected and re-written before becoming so corrupted that valid data cannot be recovered. The sometimes conflicting needs to maintain data integrity and system performance are balanced by deferring execution of some of the corrective action when the memory system has other high priority operations to perform. In a memory system utilizing very large units of erase, the corrective process is executed in a manner that is consistent with efficiently rewriting an amount of data much less than the capacity of a unit of erase. Data is rewritten when severe errors are found during read operations. Portions of data are corrected and copied within the time limit for read operation. Corrected portions are written to dedicated blocks.

摘要： In a non-volatile memory storage system such as a flash EEPROM system, a controller switches the manner in which data sectors are mapped into blocks and metablocks of the memory in response to host programming and controller data consolidation patterns, in order to improve performance and reduce wear. Data are programmed into the memory with different degrees of parallelism.

摘要： An improved flash EEPROM memory-based storage subsystem includes one or more flash memory arrays, each with three data registers and a controller circuit. During a flash program operation, one data register is used to control the program operation, a second register is used to hold the target data value, and a third register is used to load the next sector's data. Subsequent to a flash program operation, a sector's data are read from a flash array into the first data register and compared to the target data stored in the second register. When the data is verified good, the data from the third register is copied into the first and second registers for the next program operation. This creates an improved performance system that doesn't suffer data transfer latency during program operations that require data verification after the program operation is complete. Alternate embodiments perform the comparison using two register implementations and a single register implementations. The post-writer verification can be repeated and use different bias conditions for reading the data. The process can be automatic or executed by command that can specify the read conditions.

摘要： A portable memory storage device is disclosed where access to information on the device is granted only upon proper biometric authentication of a user. The device includes a controller, a non- volatile memory which may be a flash memory, and a biometric scanner system for controlling access to the information within the non-volatile memory. Each of the controller, non volatile memory and biometric scanner system may be mounted in a base of the portable device, with the biometric system having an exposed surface on a top portion of the base for accepting biometric data such as a fingerprint. A cover is provided which includes a USB connector capable of mating within a USB port of the host device to establish communications between the portable and host devices. The cover also covers the exposed portion of the biometric scanner to protect the sensor when the portable memory storage device is not in use.

摘要： A memory device for using time from a trusted host device and a method for use therewith are disclosed. In one embodiment, an application on a memory device receives a request to perform a time-based operation from an entity authenticated by the memory device, wherein the entity is running on a host device. The application selects time from the host device instead of time from a time module on the memory device to perform the time-based operation and uses the time from the host device to perform the time-based operation. Other embodiments are disclosed, and each of the embodiments can be used alone or together in combination.
