    摘要： A memory system having a memory controller and several separate memory devices connected to the controller by a system bus. The memory devices each included an array of memory cells, addressing circuitry used to address the cells and an address storage circuit which stores a local address unique to each of the memory devices. The local addresses are sequentially assigned to the memory devices by selecting a first one of the devices and forwarding an address assign command to the selected device. A command decoder, having detected the address assign command, will permit a local address placed on the bus by the controller to be loaded into the selected memory device. This sequence will continue until all of the memory devices have been assigned local addresses at which time the memory devices can be accessed to perform memory read, program, erase and other operations.

    摘要： A system embodiment comprises a nonvolatile memory device, a memory, and a controller. The nonvolatile memory device includes a plurality of nonvolatile memory cells. Each nonvolatile memory cell is adapted to store at least two bits. The memory is adapted to store a program when the system powers up. The controller is adapted to implement the program to provide instructions used to program and erase nonvolatile memory cells. A method embodiment comprises loading a program into memory upon powering up a memory system, and implementing the program using a controller, including programming and erasing multi-bit nonvolatile memory cells.

    摘要： 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.

    摘要： A joint may have a multi-stage planetary gearbox between the stationary housing and the rotary housing. To accommodate different gear ratios, the rotary housing may be joined to the stationary housing by a releasable attachment. This allows portions of the planetary gearbox to be replaced so that, for instance, the last stage may be chosen as either a simple or compound differential planetary stage. To allow for different capacities, a quotient of a sum of all teeth of a sun gear of a stage and of the ring gear with which the planetary gears of the stage mesh to both the number three and the number four yields an integer. In this way, the stage may be provided with either three or four planetary gears. The gearbox may have a ring gear common to a plurality of simple planetary stages. Where the final stage is a simple planetary stage, the carrier may be provided with a flange extending around, and bearing mounted to, the common ring gear. To reduce weight and increase robustness, the planetary gears of a stage are retained on their carrier by a bumper ring provided between carriers. An angle sensor may be provided between the stationary and rotary housings.
