    摘要: A semiconductor device includes an internal power supply, at least one semiconductor circuit block, a delay circuit, and a detecting circuit. The internal power supply outputs an initialization completion signal when initialized. The semiconductor circuit block operates on the basis of a voltage generated by the internal power supply. The delay circuit delays the initialization completion signal. The detecting circuit commands the semiconductor circuit block to start operations in response to the initialization completion signal delayed by the delay circuit and an externally input first input signal.

    摘要: A semiconductor integrated circuit device includes a memory, /CE transition detector, address transition detector, /WE transition detector and controller. The controller includes a timeout circuit. The timeout circuit generates an internal circuit control signal with preset width to control access to the memory based on detection results of the above transition detectors. The operation of the memory is controlled by the timeout circuit at the read time. The operation of the memory is controlled by the timeout circuit when transition of the end of a /WE signal is detected by the /WE transition detector before a timing specified by the timeout circuit at the write time. Further, the operation of the memory is controlled in response to the transition of the /WE signal when the transition of the end of the /WE signal is detected by the /WE transition detector after passage of the above timing.

    摘要: A chain type ferroelectric random access memory has a memory cell unit including ferroelectric memory cells electrically connected in series to each other, a plate line connected to an electrode of the memory cell unit, a bit line connected to the other electrode of the memory cell unit via a switching transistor, a sense amplifier which amplifies the voltages of this bit line and its complementary bit line, and a transistor inserted between the switching transistor and the sense amplifier. A value, being the minimum value of the gate voltage in the transistor obtained during elevation of the plate line voltage and comparative amplification, is smaller than a value, being the maximum value of the gate voltage in the transistor obtained during fall of the plate line voltage and comparative amplification. With these features, decrease in the accumulated charge of polarization in the memory cell is reduced and occurrence of disturb is prevented during read/write operations.

    摘要: A semiconductor integrated circuit device includes an address buffer which receives an address signal that indicates an address of a memory cell array, a latch circuit which latches the data, and an address transition detection circuit which detects transition of the address. During the access operation of the memory cell array, an address at the operation start time is latched by the latch circuit. After the end of the operation of the memory cell array, an address that is currently input to the address buffer is latched by the latch circuit. If the received address signal is data different from the latch data, a control signal that controls the cycle operation of the memory cell array for a predetermined period is generated on the basis of the detection result from the address transition detection circuit.
