When the child block exists in the flash memory, the target data is written into the child block.

Abstract: A plurality of memory devices of mixed type (e.g., DRAMs, SRAMs, MRAMs and NAND-, NOR- and AND-type Flash memories) having associated device type information is serially interconnected. A serial input (SI) containing a device type (DT) and a device identifier (ID) is fed to one device of the serial interconnection. Upon a match between the fed DT matches the DT of the device, the fed ID is latched in a register of the device and an ID for another device is generated, which is then transferred to the next device in the serial interconnection. Otherwise, ID generation is skipped. These steps are performed in all devices. Thus, sequential IDs are generated for the different device types and also the total number of each device type is recognized. If the fed DT is “don't care”, sequential IDs are generated for all devices and the total number of the devices is recognized.

Generally, the robotic system receives a first move instruction which commands a first robot to move a first tape cartridge from a shelf to a first tape drive to be loaded therein.

Abstract: The invention relates to a compressed data managing system and method for circular buffer. By using the system and method of the invention, when storing the compressed data in a circular buffer and an event occurs, the hardware compression mechanism can stop immediately, without jeopardizing the decompression of the compressed data.

Since when an error occurs, the system might enter the unstable state, this could cause that the tracers fail to write the last compressed data into the trace memory.

[Solving Means] The fact that a physical address [2000] is a device (Recording Device) that a photo player 370B controls in place of the physical address [2000] is set by a user in the photo player 370B.
