摘要: 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.

摘要: Layouts for data pads on a semiconductor die are disclosed. An apparatus may include circuits, a first edge, a second edge perpendicular to the first edge, a third edge opposite the first edge, and a fourth edge opposite the second edge. The apparatus may also include data pads variously electrically coupled to the circuits. The data pads may include a data pad positioned a first distance from the first edge and a second distance from the second edge. The apparatus may also include dummy data pads electrically isolated from the circuits. The dummy data pads may include a dummy data pad positioned substantially the first distance from the first edge and substantially the second distance from the fourth edge. Associated systems and methods are also disclosed.

摘要: Apparatuses, systems, and methods for counter based read clocks in stacked memory devices. An interface die provides a read command to a core die, which reads data with timing based on the read command provides that data to a read FIFO circuit of the core die. A delay time after providing the read command, the interface die begins providing a counter-based clock signal which operates an output of the read FIFO. The counter-based clock signal operates on a different time domain (e.g., a faster frequency) than the timing of the read command.

摘要: Methods and apparatuses are provided for aligning read data in a stacked semiconductor device. An example apparatus includes a stacked semiconductor device comprising stacked first and second die. The stacked semiconductor device includes a first path having a first align (first die) and second align (second die) circuits for providing read data from the second die and a second path having a first replica align (first die) and second replica align (second die) circuits. During a timing align operation, a first control circuit sets the first align and replica align circuits to a first delay value based on a propagation delay of a clock signal through the second replica align circuit. After setting of the first delay value, a second control circuit sets the second align and replica align circuits to a second delay value based on a difference in propagation delays through the first and second replica align circuits.
