Abstract
A memory interface comprising a first data input for receiving a data line to be stored in memory, a bad chip register containing a bad chip value for identifying a bad memory chip of a memory device to be used with the memory interface, and a write shift logic circuit receiving the data line from the first data input. The data line contains a plurality of data bits and a plurality of check bits, the check bits being logically appended to one end of the data bits. The write shift logic, in response to the bad chip value, causes a portion of the data line to be shifted toward the one end of the bad memory chip.
