Transmission failure feedback schemes for reducing crosstalk

A method, comprising:

• receiving, by a memory device from a controller over a plurality of data lines, data to be written to an array of memory cells of the memory device;
• determining, by the memory device, a timing offset for transmitting a checksum for the data;
• and
• transmitting, from the memory device to the controller, the checksum at a transmit time that is shifted according to the timing offset.

A method, comprising:

• transmitting, from a controller and over a plurality of data lines coupled with a memory device, data to be written to an array of memory cells of the memory device as part of a write operation;
• transmitting, over an error detection code (EDC) line coupled with the memory device during the write operation, checksum information for the transmitted data;
• and
• receiving, by the controller from the memory device, transmission failure information for the write operation indicating an error in the data based at least in part on the transmitted checksum information, wherein the transmission failure information for the write operation is received over a first line coupled with the controller and the memory device, the first line being different than the EDC line.

A device, comprising:

• an array of memory cells;
• a receiver coupled with a plurality of data lines and an error detection code (EDC) line, the receiver configured to receive data to be written to the array of memory cells via the plurality of data lines as part of a write operation and to receive checksum information during the write operation, the checksum information related to data received over the plurality of data lines;
• a comparator configured to detect errors in the data based at least in part on the checksum information;
• and
• one or more lines coupled with a controller and configured to transmit, from the device to the controller, at least one of a clock signal or transmission failure information for the write operation indicating a detected error in the data, the one or more lines being different than the EDC line.
