    摘要: A memory circuit incorporating a current-mirror type amplifier which directly amplifies a varied potential of a pair of bit lines. As soon as the word line goes High, the current-mirror type amplifier is simultaneously activated to amplify a minimal difference (100 mV) of potential between these bit lines. Data signal outputted from the current-mirror type amplifier is then transmitted to a read-only signal line. As a result, data is quickly read out before a built-in sense amplifier completes amplification, thus quickly achieving an accessing operation at extremely fast speed.

    摘要: A dynamic random access memory (DRAM) having a plurality of word lines and a plurality of bit line pairs comprises circuitry for applying an equalizing potential to either one or the other bit line of the paired bit lines to equalize (1) a first difference between a first potential and a second potential and (2) a second difference between the first potential and a third potential, for balanced read out of the paired bit lines. The first potential appears on a reference bit line paired with a bit line connected to a memory cell selected by an external address prior to sensing thereof, the second potential appears on the bit line when the selected memory cell contains "H" level data and the third potential appears on the bit line when the selected memory cell contains "L" level data. Each bit line pair has circuitry for adjusting bit line potentials consisting of a pair of capacitors having their electrodes connected to respective bit lines of an associated bit line pair in a corresponding column, and a pair of dummy word lines running parallel to the plurality of word lines, connected to respective other electrodes of the pair of capacitors. When a memory cell, connected to a bit line in a bit line pair, is selected, the potential of a dummy word line capacitively coupled to the other bit line in the bit line pair is rendered active before a sense amplifier is made active for a sensing operation.

    摘要: A semiconductor memory device such as a static RAM (Random Access Memory) device comprises a ground connection circuit of n channel field effect transistors connected between two I/O lines and the ground. The precharge circuit for precharging and the ground connection circuit both operate in response to the signal which is in synchronization with an externally applied external chip select signal. Therefore, the access delay derived from the fluctuation of the supply voltage generated before the change of the external chip select signal can be prevented.

    摘要: A MOS dynamic type RAM comprises memory cells (10), dummy cells (11), bit line pairs (BL, BL), word lines (WL), dummy word lines (DWL) and sense amplifiers (12). In a non-active cycle, the potentials of each pair of bit lines (BL, BL) are precharged at 1/2 of a supply potential V.sub.CC. Each sense amplifier (12) operates in an active cycle following the non-active cycle, while each active pull-up circuit (13) pulls up the potential of a higher level one of the pair of bit lines to V.sub.CC. This active cycle is defined by an internal RAS internal signal, which is generated by a NAND circuit (27) in response to an external RAS signal and an RPW signal obtained by delaying the external RAS signal by a delay circuit (20) and having a trailing edge obtained by delaying the trailing edge of the external RAS signal by a prescribed period.

    摘要: A dummy word line driving circuit for a MOS dynamic RAM comprises a dummy word line controller connected to each end of a pair of dummy word lines. A sub-decode signal which is opposite to the one inputted to a dummy word driver and a dummy set signal for writing a bit line information into a not-selected dummy cell are inputted to the dummy word line controller. Means for applying a dummy equalizing signal is connected to two full-sized dummy cells, for equalizing the two before the dummy word line is driven. The two full-sized dummy cells are equalized by the signal, resulting in a charge amount, which is to be a reference value, of a half of a full-sized memory cell.
