摘要： In a static memory, a memory cell is constituted by only the same-channel MOSFETs. With the MOSFETs of the same channel, no well isolation region is required, and a cell size can be decreased. Moreover, the high potential side power source of a flip-flop can be used as a read word line. Thus the read word line can be driven by an ECL logic circuit.

摘要： When an address transition detector detects a transition of an address signal, it produces an address transition detect signal. The signal drives a bit line initializing circuit which in turn initializes paired bit lines, and initializes the paired output lines of a sense amplifier. At the same time, a clock signal generator generates a clock signal for a predetermined period of time in accordance with the address transition detect signal. The clock signal is supplied to the sense amplifier and a data output circuit. The sense amplifier is active during a period that the clock signal from the clock signal generator is in an effective level. The output terminal of the data output circuit is placed in a high impedance state during the period that the clock signal is in an effective level. During the other periods than the effective level period, the data output circuit produces a signal corresponding to the data as is read out of a memory cell and outputted by the sense amplifier.

摘要： In a selected column, a pull-up transistor pair is not selected but, instead, a transmission gate transistor pair is selected. In the read mode, the transmission gate transistor pair serves as pull-up loads between the bit line pair. However, the transmission gate transistor pair is kept off until the voltage across the bit line pair is decreased from the power supply potential level to the threshold voltage level of the transmission gate transistors. Therefore, no DC current path is formed in the bit line pair when the voltage across the bit line pair is within a range from a voltage equal to the power supply potential level to a potential lower than the power supply potential by an amount equal to the threshold voltage level, and the rate of increase of a potential difference across the bit line pair is determined by a pull-in current of the memory cell. Therefore, a high-speed sense operation can be realized. In the write mode, the transmission gate transistor pair serves a bit line pull-up function. Since no normally-ON bit line load transistor is arranged, no direct current path including the bit line pair is present, and hence, low power consumption can be achieved.

摘要翻译： 在选定的列中，不选择上拉晶体管对，而是选择传输栅极晶体管对。 在读取模式下，传输栅极晶体管对用作位线对之间的上拉负载。 然而，传输栅极晶体管对保持截止，直到位线对上的电压从电源电位电平降低到传输栅极晶体管的阈值电压电平。 因此，当位线对上的电压在等于电源电位电平的电压到低于电源电位的电位的范围内时，在位线对中不形成直流电流路径， 阈值电压电平，并且位线对上的电位差的增加速率由存储单元的引入电流决定。 因此，可以实现高速感测操作。 在写入模式下，传输栅极晶体管对用于位线上拉功能。 由于没有布置正常导通的位线负载晶体管，所以不存在包括位线对的直流电路，因此可以实现低功耗。
