A plurality of stacked memory device die and a logic circuit are connected to each other through a plurality of conductors. The stacked memory device die are arranged in a plurality of vaults. The logic circuit die serves as a memory interface device to a memory access device, such as a processor. The logic circuit die includes a plurality of link interfaces and downstream targets for transmitting received data to the vaults. The logic circuit die includes a packet builder and broadcaster configured to receive command, address and data signals over separate interfaces from a conventional tester, format the signals into a packet and broadcast the signals to a plurality of vaults.
