Title: Semiconductor integrated circuit
Inventor: TANAKA KIICHI
IPC: G06F3/00
Filed: 1990-05-30
Abstract: PURPOSE:To shorten a cycle time and to improve operation speed by generating a clock whose duty is arbitrarily set and controlling a positive phase clocked buffer based on the output in a semiconductors integrated circuit having a dynamic bus. CONSTITUTION:A duty setting circuit 1 outputs the clock phi whose duty is synchronized with that of a reference clock CLK is set. When the clock phiis L, a P-transistor (TR) Tr1 is turned on, precharges a dynamic bus 3 to H, and the positive phase clocked buffer 2 comes to an input prohibition state. When the clock phi is H, N-TRTr2 is turned on, the bus 3 is discharged and it comes to L when sampling data SD input is in a high level. The buffer 2 comes to an input permission state and inputs L and holds it till the rise of the next clock phi. When the duty of the clock phi is set to larger than the duty of clock CLK, the cycling period of the discharge period of the bus 3 can considerably be secured even in the same cycle time, and the cycle time can be shortened without altering the driving capacity of a sampling transistor, whereby operation speed can be improved.
