Abstract: PROBLEM TO BE SOLVED: To obtain a high reading margin and to prevent increase of the whole area and deterioration of an AC characteristic by detecting a leak current of a memory cell during its nonselected time, supplying a current equivalent to this leak current as a load current to a sense node and making this current to flow out of the sense node at the selecting time of sensing a data. SOLUTION: At the leak checking time, a current of a leak current source 36 is supplied in place of the load current to be generated by a load circuit 38 at the read-out time to the input node N1 of a differential amplifier 33 in a sense amplifier circuit. Then, at the time of reading out a data, the leak current source 36 is connected to a bit line BL, and a fixed current flows from the bit line BL, so as to prevent a potential of the bit line BL from rising at the time of its long cycle operiod. A value of a load circuit 46 of a reference line RL on the reference side is not required to be reduced because this can be used in common with the leak current source 36 at the leak checking time. Consequently, even at the time of checking a leak current by increasing an amplitude of the bit line BL, a high reading margin can be obtained, and the circuit area is prevented from increasing.

Title: Current detector
Inventor: ABE NORIO
IPC: G01R31/08
Filed: 1995-02-08
Abstract: PURPOSE: To obtain a high sensitivity current detector which can detect even a low current passing through a current transformer by inserting a battery, having voltage lower than the emission starting voltage of a light emitting element, in the forward direction of the light emitting element. CONSTITUTION: A battery 4 having voltage lower than the emission voltage of a light emitting element 2 is inserted in the forward direction of the light emitting element 2 being applied with the output from an AC unit 1 mounted on a wire A to be measured thus applying a bias voltage. With such battery bias, the light emitting element 2 emits light even with a low passing current and the detection sensitivity is enhanced by a figure or more. When the bias voltage is too high, the light emitting element 2 emits light uselessly and thereby the bias voltage is set lower than the emission starting voltage. The battery 4 may be replaced by a DC power supply which can regulate the current finely. In this case, detection sensitivity is further enhanced by regulating the DC power supply finely thereby regulating the bias voltage.
