A technique synchronizes data retrieved from memory devices at a memory controller of a high-speed memory subsystem. A fluid access structure provides a fluid access region to a selected subset of sample wells from an array of sample wells. Each of the fluid component inlets is adapted to communicate with a source of a different fluid component. For reverse arthroplasty, the method includes attaching the adaptor to the glenoid and the cup to the stem. As a result, according to the present invention, a power supply noise between IO is absorbed and there is provided an excellent effect on an EMI and an EMS especially.
