    • A high-speed sense current amplifier with a low power consumption for a memory cell, the sense current amplifier having: a first current mirror circuit, which amplifies a memory signal current received from the memory cell via a memory signal line and outputs it at a signal output of the sense current amplifier; a second current mirror circuit, which generates a setting current in a manner dependent on the received memory signal current; and an adjustable reference current source, which outputs a reference current to the signal output of the sense current amplifier, the magnitude of the output reference current being set, via a setting line, in a manner dependent on the setting current generated by the second current mirror circuit.
