    • A logic block of a memory (LSI) with logic functions includes RAM macrocells (RAMO-RAM7) and a centrally located gate array (GAO-GA5). Clock pulse shaping circuits (CSPO, CSP1) and input/output portion (I/O) surround the logic block. The logic block power supply includes a smoothing capacitor (CC) that is substantially the same size as a cell (GC) of the gate array. Each RAM macrocell has memory mats (MATOO-MAT21), word lines (WO-W127), data lines (DO-D7), and peripheral circuits (MPCOO-MPC21), which includes an address decoder and a sense amp (SAO). An input unit cell (ICO) receives ECL level signals and outputs ECL level signals (FIG. 5 ) and MOS level signals (FIG. 6 ). The input unit cells and analogous output unit cells (OCO) are selectively used singly or in parallel to accommodate signals of different form and driving capability. A wiring line replacement region (LRP) connects memory macrocell wiring lines with logic block wiring lines. A sequence control circuit cell or aligner (ALNO, ALN1) contiguous to the RAM macrocells transmits output signals to the logic block on the wiring lines. A clock signal distribution circuit (CDA) is arranged centrally of the RAM macrocells for distributing ECL level clock signals. The clock signal distribution circuit includes clock switch amplifier circuits (CSAO-CSA9) including bipolar transistors and MOSFETs (FIG. 23 ).
    • 具有逻辑功能的存储器(LSI)的逻辑块包括RAM宏单元(RAMO-RAM7)和位于中心的门阵列(GAO-GA5)。 时钟脉冲整形电路(CSPO,CSP1)和输入/输出部分(I / O)围绕逻辑块。 逻辑块电源包括与门阵列的单元(GC)基本相同的尺寸的平滑电容器(CC)。 每个RAM宏单元具有包括地址解码器和读出放大器(SAO)的存储器垫(MATOO-MAT21),字线(WO-W127),数据线(_DO-_D7)和外围电路(MPCOO-MPC21)。 输入单元单元(ICO)接收ECL电平信号并输出​​ECL电平信号(图5)和MOS电平信号(图6)。 输入单元单元和类似输出单元单元(OCO)可以单独或并行选择性地使用,以适应不同形式和驱动能力的信号。 布线更换区域(LRP)将存储器宏单元布线与逻辑块布线相连。 与RAM宏单元相邻的序列控制电路单元或对准器(ALNO,ALN1)将输出信号发送到布线上的逻辑块。 时钟信号分配电路(CDA)被布置在RAM宏单元的中央以分配ECL电平时钟信号。 时钟信号分配电路包括包括双极晶体管和MOSFET的时钟转换放大器电路(CSAO-CSA9)(图23)。

    • A semiconductor memory device having a plurality of memory arrays in which static memory cells are disposed in a lattice arrangement at intersections of word lines and complementary data lines. The load circuits thereof are characterized as having a varying impedance effected by the combination of a first pair of P-channel MOSFETs disposed between the complementary data lines and a first node supplied with a first supply voltage and kept normally in an ON-state, and a pair of transistors, such as a second pair of P-channel MOSFETs, similarly connected as the first pair of P-channel MOSFETs and which are turned off selectively in accordance with a control signal corresponding to a predetermined selection timing signal in a write-in mode. The semiconductor memory device has a plurality of switching circuits which are coupled between the plurality of complementary data lines and a pair of data read and write lines. Each such switching circuit has a first pair of N-channel MOSFETs for selectively coupling the data input circuit of the memory device to a corresponding pair of complementary data lines via the pair of write data lines during a data write-in mode and a pair of P-channel MOSFETs for selectively coupling the corresponding pair of complementary data lines to the data output circuit via the pair of read data lines during the data read-out mode thereof.
