Integrated circuit memory devices support write and read burst modes of operation with uniformly short interconnect paths that provide high-speed memory access timing characteristics. Pumping means are provided for pumping gas into the reservoir to transfer the irrigating liquid from the reservoir to the probe. The MEMS device is mounted in the shell and electrically coupled to the lead frame through wire bonds directed through the connection window. The second linkage assembly pivots to the first linkage assembly and the base, respectively. The cool air line disposed on the cool air guide member to supply the ice making tray guides the cool air supplied from the cool air supplying device to move along the surrounding of the ice making tray, thereby uniformly cooling down the ice making tray.
