    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: An address transition detecting circuit detects on address transition signal generated during the writing of input data into a static random access memory (SRAM) and generates an address detection signal as a monostable pulse of a predetermined length. A bit line precharge and equalize signals generating circuit generates, in synchronization with the address transition detection signal and an input signal on a write data line, a bit line precharge signal and bit line equalize signal which are supplied to their columns in memory. At a time of reading, the bit line precharge and equalize signals generating circuit supplies a high level potential to paired data lines to prevent a data entry from being made into the paired write data lines by a resetting operation. At a time of writing, a write data buffer circuit supplies complementary data to the paired write data lines and prevents a data signal entry from being made by a presetting operation onto the paired write data lines, for a predetermined period of time, in synchronization with the address transition detection signal. It is, therefore, possible to prevent an input signal entry for a predetermined period of time by a resetting operation and hence prevent a write error.

    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.
