    摘要: Disclosed herein is a semiconductor memory which is capable of performing data reading without a faulty operation irrespective of the span of an address skew period. In detecting whether an address transition has been made and precharging a bit line formed in a memory cell array when a certain delay period has elapsed after the address transition is detected, the delay period is adjusted based on a delay period extension signal.

    摘要: The present invention provides a delay circuit in which normal CMOS type inverters and modified inverters added with delay PMOSs on the power supply voltage VDD terminal side are alternately cascade-connected. A correction circuit that supplies a control signal to the gates of the delay PMOSs is provided in association with the delay circuit. The correction circuit comprises a PMOS diode-connected in the forward direction, and resistors that connect the drain of the PMOS to the ground voltage VSS terminal side. The correction circuit outputs the control signal from an internal node provided between the resistors. Thus, when a power supply voltage rises, the voltage of the control signal also rises. Hence, gate-to-source voltages of the delay PMOSs are kept constant, and drain currents remain unchanged and a delay time is kept constant as well.

    摘要: A semiconductor memory device includes an array of memory cells and an adjustment circuit for adjusting the pulse width of an address transition detect equalizer (ATDEQ) signal. The adjustment circuit receives an address transition detection (ATD) signal and is responsive to the level changes of voltages Vp and Vn to adjust the pulse width of the ATDEQ signal accordingly. The resulting signal ATDEQ is supplied to a power supply circuit for a bit line selector for selecting a bit line of the array of memory cells. The device can thus accomplish the readouts of bit “0” and bit “1” in a state less liable to delay.

    摘要: A semiconductor integrated circuit comprises a plurality of memory cell blocks each including a comparing cell which detects a current level and data cells which store data therein, a plurality of reference voltage determining circuits each of which determines a second reference voltage in accordance with a first reference voltage and the output of the comparing cell, and amplifiers each of which compares the data stored in the data cell and the output of the reference voltage determining circuit and amplifies the result of comparison. The outputs of the comparing cells are short-circuited in a predetermined combination. Owing to the configuration of the semiconductor integrated circuit, misdetection of each reading cell due to process variations related to each individual comparing cell can be prevented and yield enhancement can be achieved. Further, such a configuration leads to a cost reduction.
