Abstract:
A memory device having a pipe counter, said pipe counter comprising:a clock input section for logically combining an external signal and a level row address strobe signal to apply a clock signal to a clock terminal of the pipe counter; anda reset signal input section for receiving a latency signal and a power signal to apply a reset signal to a reset terminal of the pipe counter,wherein an output of said pipe counter is comprised of first through N-th flip-flops serially connected together, each of said flip-flops having a clock terminal, a clock bar terminal, a data input terminal, and a reset terminal, and providing an output signal, the clock terminal of each of the flip-flops receives an output signal from the clock input section, the clock bar terminal of each of the flip-flops receives a signal opposite in phase to the output signal of the clock input section, the reset terminal of each of the flip-flops receives the reset signal outputted from the reset signal input section, the data input terminal of the first flip-flop receives a value which is the result of the output signals of the first through (N-1)-th flip-flops, and the data input terminals of the second through N-th flip-flops receives the output signals of the first through (N-1)-th flip-flops respectively.
