Abstract

An integrated circuit memory that contains a device for the precharging and reading of the bit lines, including a precharging element, a current-voltage converter and a read circuit, further contains a test circuit to isolate the output of the converter from the precharging element and from the read circuit, to apply a test voltage to a cell of the memory through the converter and to measure the current in the cell.
