ABSTRACT:
A plurality of devices or memories, preferably dynamic random access memories (DRAMs), are used with their output terminals connected together, and the devices or DRAMs output data signals successively in response to externally applied output enable signals. A latch circuit is provided at the output terminal of each device or DRAM. The latch circuits hold not only the output signal of the DRAM to which it belongs but also the commonly connected output signal of another DRAM in response thereto. Consequently, the output signal from any one DRAM is held by the latch circuits until an output signal is provided from another DRAM. Thus, an accurate common output signal can be obtained without being affected by external noise or the requirement for extremely accurate timing signals.
