    摘要: A semiconductor integrated circuit includes a limiter circuit for outputting a voltage determining flag in order to set a boosted voltage level of a booster circuit to be a predetermined value, and a monitoring circuit for monitoring a monitoring node of the limiter circuit to output a monitoring signal for the stabilization of a boosted voltage to a first external terminal. The monitoring circuit detects a first level change of the voltage determining flag from “H” to “L” after the starting of the operation of the limiter circuit, by means of a comparator, to which an external power supply voltage and external reference voltage supplied from second and third external terminals are given, and thereafter, outputs a monitoring signal for holding a constant logical level during the operation of the limiter circuit. In order to provide a voltage trimming function, a voltage intended to be set in an external terminal may be given from the outside to deactivate a feedback system of the limiter circuit to operate a resistance value of the limiter circuit to detect and store a limiter flag. Thus, there is provided a semiconductor integrated circuit capable of simply monitoring the output voltage state of an internal power supply circuit by the external terminal and easily trimming an internal voltage.

The second circuit generates a second current which is preset. The third circuit compares the first current with the second current. The value of “1” or “0” of binary logic data of the one end of the plurality of latch circuits is detected based on a result of the comparison between the first current and the second current.

    摘要: An INVSRC node and a SAREF node are previously precharged. After a potential on a bit line is reset, the bit line (BLS node) is precharged. In this event, a clamp MOS transistor in a sense amplifier is in ON state, and an SA node is also precharged simultaneously. A precharge level is set to a value lower than a threshold voltage of an inverter. Subsequently, when SAEN transitions to “H,” a sense operation is performed. For reading data “0,” the SA node is rapidly increased to Vdd. For reading data “1,” the SA node slowly approaches to Vss. A change in the potential at the SA node is detected by the inverter.
