<p>Memory systems, systems and methods are disclosed that may include a plurality of stacked memory device dice and a logic die connected to each other by through silicon vias. One such logic die includes an error code generator that generates error checking codes corresponding to write data. The error checking codes are stored in the memory device dice and are subsequently compared to error checking codes generated from data subsequently read from the memory device dice. In the event the codes do not match, an error signal can be generated. The logic die may contain a controller that records the address from which the data was read. The controller or memory access device may redirect accesses to the memory device dice at the recorded addresses. The controller can also examine addresses or data resulting in the error signals being generated to identify faults in the through silicon vias.</p> |
