Memory architecture including response manager for error correction circuit

A circuit, comprising:

• error correction circuitry configured to;
• receive a data packet;
• determine whether a correctable error is present in the data packet, and in response thereto output a correctable error flag indicating presence or absence of the correctable error in the data packet;
• determine whether an uncorrectable error is present in the data packet, and in response thereto output an uncorrectable error flag indicating presence or absence of the uncorrectable error in the data packet;
• and
• a response manager circuit configured to receive the correctable error flag and the uncorrectable error flag, and:
• in an availability mode, generate an output indicating that a correctable error was present in the data packet if the correctable error flag indicates presence of the correctable error in the data packet, and generate an output indicating that an uncorrectable error was present in the data packet if the uncorrectable error flag indicates presence of the uncorrectable error in the data packet;
• and
• in a coverage mode, generate an output indicating that a correctable error was potentially present in the data packet but should be treated as an uncorrectable error if the correctable error flag indicates presence of the correctable error in the data packet, and generate an output indicating that an uncorrectable error was present in the data packet if the uncorrectable error flag indicates presence of the uncorrectable error in the data packet.

A method of operating an electronic device, comprising:

• a) receiving a data packet;
• b) determining whether a correctable error is present in the data packet;
• c) determining whether an uncorrectable error is present in the data packet;
• d) determining whether to enter coverage mode or availability mode;
• e) in the availability mode, indicating that a correctable error was present in the data packet, and generate an output indicating that an uncorrectable error was present in the data packet if an uncorrectable error was in the data packet;
• and
• f) in the coverage mode, indicating that a correctable error was potentially present in the data packet but should be treated as an uncorrectable error if a correctable error was present in the data packet, and generate an output indicating that an uncorrectable error was present in the data packet if an uncorrectable error was present in the data packet.
