Claim:
1. Current sense read amplifier for use as a read amplifier in a memory arrangement of memory cell groups, wherein in each of said memory cell groups cells includes at least one read port connected to a read amplifier by a bitline, and wherein said read amplifiers are connected to a data output, the current sense read amplifier comprising: a voltage regulator coupled to the bitline to keep a bitline voltage at a constant voltage level below a power supply voltage and above a ground; a measurement coupled to the bitline circuit to detect a high current value and a low current value in a input signal; a configuration unit coupled to the measurement circuit to enable or disable the measurement circuit; and a generator coupled to the bitline to generate a high voltage level output signal when the high current value is detected and to generate a low voltage level output signal when the low current level value is detected.
