    摘要: An electrically programmable read only memory is equipped with latch circuits for sequentially introducing series signals which are fed through external terminals. The converter includes sequentially operated switch elements and latch circuits in order to convert the series signals into parallel signals. The thus converted parallel signals are written simultaneously in a memory array via address decoder operated selection switch elements. According to this method, the writing operations into the memory array can be conducted at a high speed even when one writing operation is relatively long as a result of the parallel signal action.

    摘要: In an oscillation circuit wherein three or a greater odd number of inverters each of which is composed of a load FET and a driving FET are connected in cascade, a capacitor is connected between the input and output of at least one of the inverters so as to construct a Miller integrator, and the output of the final-stage inverter is connected to the input of the first-stage inverter, the improvement comprising the fact that impedance means, such as resistance, which has a positive temperature coefficient is connected in series with the capacitor, whereby the oscillation frequency of the oscillation circuit is prevented from fluctuating due to a change of the ambient temperature.
