摘要： A method of performing multiple operations on a flash memory device is described. This is made possible through the implementation of multiple partitions within the flash memory. The partitions are used to store data, application code, and system code. Low level functions within the system code process the data and handle preemption functions within the flash memory.

摘要： A method of directly reading addresses from flash memory using an object tracking table is described. Some applications such as K-Java typically require their data to be stored contiguous in memory. In order to achieve contiguous memory space, free memory is compressed during reclaim. The data compression may alter the address locations within the application files. The object tracking table helps enable direct flash access to modify and update flash object data.

摘要： A cache memory for operations to a flash memory. A flash memory manager places flash write and flash erase commands into a cache, for subsequent execution by the flash memory. The cache can replace a queue used in conventional flash memory systems. A foreground manager can perform a check for available space in the flash memory, break up the command into appropriate cache entries, and write the entries into the cache. A background manager can subsequently read the entries from cache and execute them to flash memory, deleting each cache entry as it is posted to flash memory. The cache can include multiple sets of tag/data arrays, each dedicated to commands with a particular priority. Relocating most conventional flash management functions from background to foreground can eliminate the possibility of “flash full” responses from the background manager, thus eliminating the need for the background manager to determine whether space will be available for the command when it is executed to flash.

摘要： A method of detecting the loss of a sector of data stored in a solid state memory disk is described. Detection is enabled by the creation of a header for each sector number during formatting. Each header includes a logical sector number equal to a sector number. Location and loss of a sector of data associated with a particular sector number is aided by a sector header translation table. The sector header translation table stores an offset, or pointer, for each sector number that points to its associated header. The method by which the sector header translation table is generated aids in the detection of lost sectors of data. Upon power-up, each offset in the sector header translation table is initialized to an initial, invalid value. Afterward, the nonvolatile semiconductor memory is scanned and the sector header translation table is modified so that for each sector number it points to the header including a logical sector number equal to the sector number. As a result, retrieving an invalid offset from the sector header translation table indicates that the sector of data associated with the sector number is lost.Circuitry for detecting the loss of sector data stored in a solid state memory disk is also described.

摘要： A method of executing states of a clean-up state machine while executing a command from a host CPU to read a sector of data stored within a memory array. First, a number of sectors of data are copied from the memory array into a sector buffer. Then, while the host CPU is reading sectors from the sector buffer, a number of states of a clean-up state machine are executed to aid in the conversion of invalid user data into free memory. Also described is a solid state memory disk that converts invalid sectors of data to free memory while executing a read command from a host CPU.

摘要： A process for releasing sectors of a flash EEPROM memory array which includes a plurality of individually erasable blocks and stores sectors of data in such blocks with a header providing a logical sector number, an indication of validity of data stored, and an indication of whether data is stored with the header. The process includes the steps of finding the header of a sector with data to be released, setting the indication of validity of the data stored to indicate that the data is invalid, and writing a new header for the sector to a new position in the array without data and with an indication that data is not attached.
