  • Patent number: 7188210
    Abstract: Data transferred from a host computer to a memory device is written into sectors whose addresses in a memory area are decoded by a decode table. Old data to be updated by the above data is erased or marked with erase flags. At a predetermined point of time, in order to create free areas, necessary data is evacuated to a primary memory media and unnecessary data indicated by erase flags is erased by a unit of predetermined memory size. Part of the memory media which has become defective is marked with a defect flag, and is replaced by an alternate area. In doing so, the decode table is rewritten to arrange the memory area.

  • Patent number: 7187738
    Abstract: A first transparent latch receives a first synchronised signal changing its logic state synchronously with respect to a clock signal. A second transparent latch receives a second synchronised signal output by the first latch. When the clock signal has a first logic state the first latch has a non-responsive state and the second latch has a responsive state, and when the clock signal has a second logic state the first latch has the responsive state and the second latch has the non-responsive state. The change in logic state of a third synchronised signal output by the second latch is guaranteed to occur in a particular half-cycle of the clock signal, irrespective of process/voltage/temperature (PVT) variations of the circuitry.
