    Abstract: An autotesting method of a cells matrix of a memory device is disclosed which comprises the steps of:

    reading the values contained in a plurality of the memory cells;
    comparing the read values with reference values;
    signalling mismatch of the read values with the reference values as an error situation; and
    storing the error situations.

    In the autotesting method, the reading, comparing, signalling, and storing steps are repeated for all the memory cells in an matrix column.
    The autotesting method according to the invention further comprises the steps of:

    storing the addresses of any columns having at least one error situation; and
    repeating all the preceding steps according to a step of scanning all the matrix columns.

    Advantageously according to the invention, all said steps are internally realized in the memory device.
    Also disclosed is a memory device with a autotesting architecture, which device is adapted to implement the autotesting method according to the invention.
