A process for color adjustment of a color monitor including a cathode-ray tube and a brightness adjustment module includes providing a nominal brightness signal downstream of a white level adjustment module for adjusting a white level and upstream of a black level adjustment module for adjusting a black level. The process also includes setting a voltage required to obtain a black color image, setting a voltage required to obtain a white color image, providing the nominal brightness signal upstream of the white level adjustment module, and setting the voltage required to obtain the black color image.

An electrically erasable and programmable memory includes a memory array having memory cells connected to word lines and bit lines. The bit lines are arranged in columns. The memory also includes read circuits connected to the bit lines and programming latches connecting the bit lines to a programming line. The memory includes a device to break the conductive paths connecting the memory cells of a column to the read circuits when data has been loaded into the latches of the column, without breaking the conductive paths that connect the latches of the column to the read circuits.
