Host error control matrix

An automotive memory system, comprising:

• a memory device comprising a plurality of memory cells configured to store data characterized by a plurality of data channels and a plurality of unit intervals;
• and
• a host system coupled with the memory device and configured to communicate the data over one or more data channels and error control information, associated with a plurality of parity bits, over a dedicated error control channel, the host system further comprising:
• an error control engine implementing a parity check matrix that indicates. for each parity bit of the plurality of parity bits, a respective set of data bits for generating the parity bit,
• wherein each of the respective sets of data bits includes multiple data channels in each of the plurality of unit intervals.

An apparatus, comprising:

• a controller associated with a host device, wherein the controller is configured to cause the apparatus to:
• generate, by an error control engine of the host device, error control information associated with a plurality of parity bits by applying a parity check matrix to data characterized by a plurality of data channels and a plurality of unit intervals, the parity check matrix indicating, for each parity bit of the plurality of parity bits, a respective set of data bits for generating the parity bit,
• wherein each of the respective sets of data bits includes multiple data channels in each of the plurality of unit intervals;
• p2 transmit, to a memory device based at least in part on generating the error control information, the data over one or more data channels and the error control information over a dedicated error control channel;
• p2 receive, from the memory device based at least in part on transmitting the data and the error control information, the data over the one or more data channels and the error control information over the dedicated error control channel;
• and
• generate, at the error control engine, second error control information by applying the parity check matrix to the data received from the memory device.
