SEMICONDUCTOR DEVICE WITH FIRST-IN-FIRST-OUT CIRCUIT

Abstract:

Apparatuses including a first-in first-out circuit are described. An example apparatus includes: a first-in first-out circuit including a first latch, a second latch and a logic circuit coupled in series. The first latch receives first data and latches the first data responsive to a first input pointer signal. The second latch receives the latched first data from the first latch and latches the received first data responsive to a second input pointer signal that has a different phase from the first input pointer signal and thus provides a second data. The logic circuit receives the second data and an output pointer signal and further provides an output data responsive to the output pointer signal.
