Abstract: A memory system includes an array of solid state memory devices which are in communication with and under the control of a controller module via a device bus with very few lines. This forms an integrated-circuit mass storage system which is contemplated to replace a mass storage system such as a disk drive memory in a computer system. Command, address and data information are serialized into component strings and multiplexed before being transferred between the controller module and the array of memory devices. The serialized information are is accompanied by a control signal to help sort out the multiplexed components. Each memory device in the array is mounted on a multi-bit mount and assigned an array address by it an array mount. An A memory device is selected by an appropriate address broadcast over the device bus, without requiring the usual dedicated select signal. A reserved array particular mount multi-bit configuration is used to unconditionally select the device mounted thereon.

Abstract: A mass storage system made of flash electrically erasable and programmable read only memory (“EEPROM”) cells organized into blocks, the blocks in turn being grouped into memory banks, is managed to even out the numbers of erase and rewrite cycles experienced by the memory banks in order to extend the service lifetime of the memory system. Since this type of memory cell becomes unusable after a finite number of erase and rewrite cycles, although in the tens of thousands of cycles, uneven use of the memory banks is avoided so that the entire memory does not become inoperative because one of its banks has reached its end of life while others of the banks are little used. Relative use of the memory banks is monitored and, in response to detection of uneven use, have their physical addresses periodically swapped for each other in order to even out their use over the lifetime of the memory.

Abstract: A file structure employed in a flash electrically erasable and programmable read only memory ("EEPROM") system and aspects of forming and using certain data fields within such a file structure. An array of rows and columns of EEPROM memory cells is divided into blocks of cells that are separately addressable for the purpose of erasing an entire block of cells at the same time. Each block contains several rows of cells with certain columns thereof storing a sector of data, typically 512 bytes of data, and other columns of cells within the same rows being used as spare cells to replace any defective sector data cells and store overhead (header) information about the block and the data sector. Such overhead information includes pointers to locations of any defective sector data cells within the block, whether the block has been mapped out in favor of another block, error correction codes for the sector data and the header information, and other similar types of information.
