Abstract
A circuit configuration for measuring or calibrating current of components in memory elements, preferably, EPROM or EEPROM memory elements, includes a memory cell field, a reference cell field, a current comparator, a digital-analog converter receiving a digital signal having digital values and outputting predetermined current values based upon receiving corresponding ones of the digital values, a first switch having an output connected to a first input of the current comparator, a first input connected to the memory cell field, and a second input connected to the reference cell field, and a second switch having an output connected to a second input of the current comparator, a first input connected to the reference cell field, and a second input connected to the digital-analog converter. The second switch can have a third input to be connected to an external current source.
