IPC: G11C11/408
Filed: 1986-09-24
Abstract: PURPOSE:To attain high speed and to reduce number of components as a whole by adopting switch tree decode structure and averaging number of MOSFETs connected to a signal line fed with each address signal. CONSTITUTION:Address signals a0, the inverse of a0 of the least significant bit in an address decoder are fed respectively to gates of five MOSFETs, address signals a1, the inverse of a1 of a 2nd order bit are fed to gates of four MOSFETs, and address signals a2, the inverse of a2 of a 3rd order bit are fed to gates of five MOSFETs. Thus, the number of MOSFETs connected to the signal line receiving each address signal is averaged. As a result, since the input gate capacity and parasitic capacitance connected to each signal line are averaged, the maximum capacity is reduced. Thus, number of MOSFETs is reduced and the reduction number is increased when number of stages of switch tree is increased. Moreover, the high speed is attained by the reduction in the capacity.
