ABSTRACT:
A memory device including first and second memory cell arrays in which are stored respectively user data and error identification and correction data. The memory device also includes first and second decoding means operationally connected to the first and the second memory cell arrays for producing select user data signals and select error identification and correction data signals. The memory device further includes error identification means operationally coupled to the first and the second decoding means. The memory device also comprises error correction means operationally connected to the first and the second decoding means and to the error identification means. Finally the memory device includes a control unit operationally connected to the second decoding means, to the error identification means and to the error correction means to enable the second decoding means and the error correction means if the error identification means detect an error in the select user data signals.
